* Remove native screen reader support
Use the "accesskit" feature flag to `eframe` instead.
[AccessKit](https://github.com/AccessKit/accesskit) is the future.
`tts` was a mess to compile on many platforms, so I no longer want
the native `tts` dependency.
* Update tts to 0.25
* Update changelogs
* Turn on all feature flags for package.metadata.docs.rs
* remove tts from deny.toml skip-tree
* Update web build scripts
* Update deny.toml
* Remove integration name (it is always eframe)
* Remove egui_web crate
* Move egui_web/CHANGELOG.md into eframe/CHANGELOG.md
* Remove all mentions of egui_web
* Remove epi crate and absorb into eframe
* egui_glow: only use puffin on native
* Remove WASM doc from CI (we don't generate it anyways!)
* Remove eframe::epi and improve eframe docs
