Remove native screen reader support (emilk#2669)

* 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
