This auto-formats all *.dart files in the repository outside of the
`engine` subdirectory and enforces that these files stay formatted with
a presubmit check.
**Reviewers:** Please carefully review all the commits except for the
one titled "formatted". The "formatted" commit was auto-generated by
running `dev/tools/format.sh -a -f`. The other commits were hand-crafted
to prepare the repo for the formatting change. I recommend reviewing the
commits one-by-one via the "Commits" tab and avoiding Github's "Files
changed" tab as it will likely slow down your browser because of the
size of this PR.

Set the `hasSelectedState` flag in all selectable widgets. This happens automatically because only selectable widgets have `Semantics.selected` set to a non-null value. When the value is propagated to `SemanticsConfiguration.isSelected`, it sets both `hasSelectedState` to true and `isSelected` as appropriate.
More progress towards https://github.com/flutter/flutter/issues/66673
Multiple fixes related to heading levels:
* Fix heading level absorption. Heading level would get erased when a semantics config is absorbed into another. With this change the highest heading level wins.
* Add `headingLevel` to the diagnostics of `SemanticsNode`.
* Add unit-tests for heading levels.
* Add an a11y use-case for headings.
Improves https://github.com/flutter/flutter/issues/46789 and general accessibility of headings.
The purpose of this PR is to temporarily skip one integration test that is blocking the changes indicated below:
(This change adds a new property in Semantics widget that would take an integer corresponding to the heading levels defined by the ARIA heading role. This is necessary in order to get proper accessibility and usability in a website for users who rely on screen readers and other assistive technologies.)
Issue fixed by this PR:

When a `TextField` is rendered before a `Navigator`, it breaks in semantics mode. This is because the framework generates the incorrect semantics tree (excludes the TextField) and when that tree gets sent to the engine, we don't get the signal to create the corresponding `<input>` element.
This happens for a few reasons:
* `ModalBarrier` uses `BlockSemantics` to drop the semantics of routes beneath the current route in `Navigator`
* `ModalBarrier` mistakenly recognizes the widget outside of the `Navigator` to be its sibling
* So we end up dropping the semantics node of the `TextField` rendered before it.
The fix is to let `Navigator` generate a semantics node so that `ModalBarrier` doesn't mistakenly think widgets outside of `Navigator` are its siblings.
`Navigator` doesn't currently do this, which causes all the nodes generated from its widget subtree to be directly attached to the parent semantics node above `Navigator` - since this is also the parent of `TextField`, it considers them siblings.

Much nicer calling API and simplifies evolving this API in the future.
I wish we could write a dart fix for this, but that's blocked on https://github.com/dart-lang/sdk/issues/54668.
This PR adds `String? identifier` to `Semantics` and `SemanticsProperties`. The `identifier` will be exposed on Android as `resource-id` and on iOS as `accessibilityIdentifier`.
Mainly targeted at #17988

### Migration
This change breaks the SemanticsUpdateBuilder API which is on the Framework<-->Engine border. For more details see [engine PR](https://github.com/flutter/engine/pull/47961).
Steps:
part 1: [engine] add `SemanticsUpdateBuilderNew` https://github.com/flutter/engine/pull/47961
**part 2: [flutter] use `SemanticsUpdateBuilderNew`** <-- we are here
part 3: [engine] update `SemanticsUpdateBuilder` to be the same as `SemanticsUpdateBuilderNew`*
part 4: [flutter] use (now updated) `SemanticsUpdateBuilder` again.
part 5: [engine] remove `SemanticsBuilderNew`
