Implement accessibility APIs via AccessKit (#2294)
* squash before rebase

* Update AccessKit, introducing support for editable spinners on Windows and an important fix for navigation order on macOS

* Restore support for increment and decrement actions in DragValue

* Avoid VoiceOver race condition bug

* fix clippy lint

* Tell AccessKit that the default action for a text edit (equivalent to a click) is to set the focus. This matters to some platform adapters.

* Refactor InputState functions for AccessKit actions

* Support the AccessKit SetValue for DragValue; this is the only way for a Windows AT to programmatically adjust the value

* Same for Slider

* Properly associate the slider label with both the slider and the drag value

* Lazily activate egui's AccessKit support

* fix clippy lint

* Update AccessKit

* More documentation, particularly around lazy activation

* Tweak one of the doc comments

* See if I can get AccessKit exempted from the 'missing backticks' lint

* Make PlatformOutput::accesskit_update an Option

* Refactor lazy activation

* Refactor node mutation (again)

* Eliminate the need for an explicit is_accesskit_active method, at least for now

* Fix doc comment

* More refactoring of tree construction; don't depend on Arc::get_mut

* Override a clippy lint; I seem to have no other choice

* Final planned refactor: a more flexible approach to hierarchy

* Last AccessKit update for this PR; includes an important macOS DPI fix

* Move and document the optional accesskit dependency

* Fix comment typo

Fix text sizes being too small (#2069)
Closes https://github.com/emilk/egui/issues/2068

Before this PR, the default font, Ubuntu-Light, was ~11% smaller
than it should have been, and the default monospace font, Hack,
was ~14% smaller. This means that setting the font size `12` in egui
would yield smaller text than using that font size in any other app.
Ooops!

The change is that this PR now takes into account the ttf properties
`units_per_em` and `height_unscaled`.

If your egui application has specified you own font sizes or text styles
you will see the text in your application grow
larger, unless you go in and compensate by dividing all font sizes by
~1.21 for Ubuntu-Light/Proportional and ~1.16 for Hack/Monospace,
and with something else if you are using a custom font!
This effects any use of `FontId`, `RichText::size`, etc.

This PR changes the default `Style::text_styles` to compensate,
so the default egui style should look the same before and after this PR.

Add `InputState::stable_dt` (#1625)
This provides a better estimate of a typical frametime in reactive mode.

From the docstring of `stable_dt`:

Time since last frame (in seconds), but gracefully handles the first frame after sleeping in reactive mode.

In reactive mode (available in e.g. `eframe`), `egui` only updates when there is new input or something animating.
This can lead to large gaps of time (sleep), leading to large [`Self::unstable_dt`].

If `egui` requested a repaint the previous frame, then `egui` will use
`stable_dt = unstable_dt;`, but if `egui` did not not request a repaint last frame,
then `egui` will assume `unstable_dt` is too large, and will use
`stable_dt = predicted_dt;`.

This means that for the first frame after a sleep,
`stable_dt` will be a prediction of the delta-time until the next frame,
and in all other situations this will be an accurate measurement of time passed
since the previous frame.

Note that a frame can still stall for various reasons, so `stable_dt` can
still be unusually large in some situations.

When animating something, it is recommended that you use something like
`stable_dt.min(0.1)` - this will give you smooth animations when the framerate is good
(even in reactive mode), but will avoid large jumps when framerate is bad,
and will effectively slow down the animation when FPS drops below 10.

Optimize tessellation of filled circles (#1616)
When painting a scatter plot we sometimes want to paint hundreds of thousands of points (filled circles) on screen every frame.

In this PR the font texture atlas is pre-populated with some filled circled of various radii. These are then used when painting (small) filled circled, which means A LOT less triangles and vertices are generated for them.

In a new benchmark we can see a 10x speedup in circle tessellation, but the the real benefit comes in the painting of these circles: since we generate a lot less vertices, the backend painter has less to do.

In a real-life scenario with a lot of things being painted (including around 100k points) I saw tessellation go from 35ms -> 7ms and painting go from 45ms -> 1ms. This means the total frame time went from 80ms to 8ms, or a 10x speedup.

Warn about Id clashes for Grid, Plot, ScrollArea, Table (#1452)
Id clashes can cause subtle bugs.

egui already warns when the same Id is used to interact with different

This adds warnings about id clashes for some widgets that store state:
Grid, Plot, ScrollArea, Table.

The PR also adds `Context::check_for_id_clash` so users who create
their own widgets can add the same type of check.

Fix code that could lead to a possible deadlock. (#1380)
* Fix code that could lead to a possible deadlock.

Drop implementations are not called until the end of a statement. The statement changed in this commit therefore took 4 read locks on a RwLock which can lead to problems if a write lock is requested between any of these read locks. The code looks like it would only hold one lock at a time but it does not drop any of the locks until after the arithmatic operations complete, which leads to this situation. See https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=996079046184329f3a9df1cd19c87da8 to see this in action. The fix is to just take one lock and share it between the three calls to num_presses, letting it drop at the end of the scope.

* Fix code that may cause a deadlock in `MenuRoot::stationary_interaction`

The issue here is related to that in 9673b8f2a08302c10ffcfd063f2dbdec4301d3e2 in that the lock is not dropped when it is expected.  Since the `RwLockReadGuard` produced by `ctx.input()` has a reference taken from it (one into `pointer`), the lock cannot be dropped until that reference is no longre valid, which is the end of the scope (in this case this function).  The following `ctx.input()` then attempts to aquire a second lock on the `RwLock`, creating the same situation that was found in the referenced commit.

This has been resolved by holding one lock on the input for the whole function.

Context::request_repaint will wake up the UI thread (#1366)
This adds a callback (set by `Context::set_request_repaint_callback`)
which integration can use to wake up the UI thread.

eframe (egui_web and egui_glow) will use this, replacing
`epi::Frame::request_repaint`.

Existing code calling `epi::Frame::request_repaint` should be changed
to instead call `egui::Context::request_repaint`.

This is the first callback added to the egui API, which otherwise is
completely driven by data.

The purpose of this is to remove the confusion between the two
`request_repaint` methods (by removing one). Furthermore, it makes
`epi::Frame` a lot simpler, allowing future simplifications to it
(perhaps no longer having it be `Send+Sync+Clone`).
