Group AccessKit nodes by `Ui` (#7386)
* closes https://github.com/emilk/egui/issues/5674

This changes egui to create an AccessKit node for each `Ui`. I'm not
sure if this alone will directly improve accessibility, but it should
make it easier to create the correct parent / child relations (e.g.
grouping menus as children of menu buttons).
Instead of having a global stack of parent ids, they are now passed via
a parent_id field in `UiBuilder`.

If having all these `GenericContainer` nodes somehow is bad for
accessibility, the PR could also be changed to only create nodes if
there is actually some accessibility info with it (the relevant is
currently commented-out in the PR). But I think screen readers should
just ignore these nodes, so it should be fine? We could also use this as
motivation to git red of some unnecessary wrapped `Ui`s, e.g.
CentralPanel creates 3 Uis when 2 should be enough (the initial Ui and a
Frame, maybe we could even only show the `Frame` if we can give it an
UiBuilder and somehow show the Frame with `Ui::new`).

Here is a screenshot from the accessibility inspector
