### Problem
When clicking on a TextEdit sometimes the cursor doesn't appear
immediately which makes it feel like the click was not registered for a
second. This is because the start time for the blinking animation is
only reset on keyboard input, but not on mouse interaction.
It's hard to tell on the video but the cursor doesn't show immediately
after clicking if the blink timer happens to be off.

### Solution
Reset the click timer every time a `TextEdit` is clicked.
Additionally, the cursor is now correctly painted on the pixel boundary.
IMO we should default to 1px cursor (instead of 2px) but that's not
included in this PR. Happy to make that change too.

This moves `egui::util::cache` to `egui::cache` (the old path is
deprecated, but still works).
It also adds the `FramePublisher` helper, which can be used to publish a
value which will be retained for this frame and the next:
``` rs
pub type MyPublisher = egui::cache::FramePublisher<MyKey, MyValue>;
// Publish:
ctx.memory_mut(|mem| {
mem.caches.cache::<MyPublisher>().set(key, value);
});
// Retrieve:
let value: Option<MyValue> = ctx.memory_mut(|mem| {
mem.caches
.cache::<MyPublisher>()
.get(key)
.clone()
})
```
* Closes https://github.com/emilk/egui/issues/5423

This lets users trigger a screenshot from anywhere, and then when they
get back the results they have some context about what part of their
code triggered the screenshot.

### Before
Notice how the cursor hides after third enter and when the line is long.
https://github.com/user-attachments/assets/8e45736e-d6c7-4dc6-94d0-213188c199ff
### After
Cursor is always visible
https://github.com/user-attachments/assets/43200683-3524-471b-990a-eb7b49385fa9
- `ScrollArea` now checks if there's a `scroll_target` in `begin`, if
there is, it saves it because it's not from its children, then restore
it in `end`.
- `TextEdit` now allocates additional space if its galley grows during
the frame. This is needed so that any surrounding `ScrollArea` can bring
the cursor to view, otherwise the cursor lays outside the the
`ScrollArea`'s `content_ui`.

cargo machete depends on cargo-platform which seems to bumped it's msrv.
Installing via --locked should fix this for now. I think it's fine to do
this manually instead of using the cargo action since it's so simple and
the action we used basically did the same (without --locked)

This adds modals to egui.
This PR
- adds a new `Modal` struct
- adds `Memory::set_modal_layer` to limit focus to a layer and above
(used by the modal struct, but could also be used by custom modal
implementations)
- adds `Memory::allows_interaction` to check if a layer is behind a
modal layer, deprecating `Layer::allows_interaction`
Current problems:
- ~When a button is focused before the modal opens, it stays focused and
you also can't hit tab to focus the next widget. Seems like focus is
"stuck" on that widget until you hit escape. This might be related to
https://github.com/emilk/egui/issues/5359~ fixed!
Possible future improvements:
- The titlebar from `window` should be made into a separate widget and
added to the modal
- The state whether the modal is open should be stored in egui
(optionally), similar to popup and menu. Ideally before this we would
refactor popup state to unify popup and menu

eframe has features for selecting between x11 and wayland. eframe does
not forward the features to glutin. This makes glutin always compile
with both backends enabled. This change forwards the feature. This
allows users of egui to compile less dependencies when they only need
one of x11, wayland.
To understand this change, read the glutin Cargo.toml [1] and the glutin
build.rs [2]. You always have to enable glutin's glx feature with the
x11 feature. The other default features (egl, wgl) stay enabled. This is
intentional so that everything continues to work as before. We could
further minimize when egl and wgl are enabled, but that is not part of
this change. There is little reason to do so because those feature
already only add dependencies when you compile glutin for the right
platform (for example wgl on windows).

For the test I added a `Harness::press_key` function. We should
eventually add these to kittest, probably via a trait one can implement
for the `Harness` but for now this should do.
As someone who uses "grey" instead of "gray", it is annoying that my
autocomplete can never find any of the "gray" color related things, so
this adds doc aliases for that.

The allows us to pass any state to the ui closure. While it is possible
to just store state in the closure itself, accessing that state after
the harness was created to e.g. read or modify it would require interior
mutability. With this change there are new `Harness::new_state`,
`Harness::run_state`, ... methods that allow passing state on each run.
This builds on top of #5301, which should be merged first

This adds a `Harness::new_ui`, which accepts a Ui closure and shows the
ui in a central panel. One big benefit is that this allows us to add a
fit_contents method that can run the ui closure with a sizing pass and
resize the "screen" based on the content size.
I also used this to add a snapshot test for the rendering_test at
different scales.

I removed the webp supported URI test given that the webp feature would
have to be enabled. I kept that webp is not supported in the other
tests.
There might need to be an additional warning in the changelog that image
support detection is now stricter.
egui never accesses the `FontDefinitions`' member fields mutably, except
in `fonts_tweak_ui` where it cloned the `FontDefinitions` object anyway.
This patch reduces system memory consumption for shared font
definitions.
And also removes some overhead from copying (e.g. for the per
`pixel_per_points` font atlas)
Also it allows to keep a copy of the font definitions outside of egui.
In my App that uses international fonts:
Before:
New:
Note: If `Arc` is not wanted, then it could ofc be abstracted away.
I know this is quite a breaking change API wise, but would like to hear
your opinion.

The `RawInput::dropped_files` documentation referred to `NativeOptions`,
but the `drag_and_drop` option was moved to `ViewportBuilder` and is now
enabled by default.
Note that drag-and-drop is not *explicitly* enabled by default here, but
rather is enabled by default in winit. We only override winit's default
if the API consumer specifies it. It might be a good idea in general to
provide explicit defaults for everything in `ViewportBuilder` so we're
not relying on winit's behavior, but that's best left for another PR.

I am preparing a separate PR that adds support for JXL with `jxl-oxide`,
which is unlikely to be added to the `image` crate anytime soon (more
context will be provided in that PR).
`jxl-oxide` makes use of the
[`array::each_mut`](https://doc.rust-lang.org/stable/std/primitive.array.html#method.each_mut)
API which was stabilized in 1.77, which is the motivation for this MSRV
bump.
Rust 1.77 was officially released to stable on 21 March, 2024.
This adds `egui_kittest::try_image_snapshot_options` and
`egui_kittest::image_snapshot_options`, as well as
`Harness::wgpu_snapshot_options` and
`Harness::try_wgpu_snapshot_options`

When mixing and matching eframe with other wgpu applications
(https://github.com/tracel-ai/burn in my case), it can be helpful to use
an existing wgpu setup to initialize eframe with. This PR changes the
WpuConfiguration (in a non-backwards compat way :/), to either take some
options how to create a wgpu setup, or an existing wgpu setup
(consisting of an instance, adapter, device and queue).

Currently `Style::override_font_id` does not affect widgets with their
`TextStyle` like `Button`s, `ComboBox`es, `CheckBox`es, etc. This PR
fixes this behavior such that all widgets using default configuration of
`RichText` are affected by this setting.
