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.

This PR fixes#92525 and introduces the following changes according to [latest iOS HIG](https://developer.apple.com/design/human-interface-guidelines/buttons#iOS-iPadOS):
- `CupertinoButton` now has a `size` property (type `enum CupertinoButtonSize`, values sm/md/lg, default `lg`) that allows the devs to apply new iOS 15+ button styles
- Previously `CupertinoButton` had a larger padding when no background color was specified. With the new HIG, that is no longer the case
- `CupertinoButton` now has a `.tinted` constructor that renders a translucent background (transparency % is brightness-dependent) and uses a different foreground color compared to `.filled`
- `CupertinoButton` now uses the `actionTextStyle` TextStyle from the given theme
- `CupertinoButton`'s child IconTheme's size will always be x1.2 the given TextStyle's size
- `CupertinoTextThemeData` now has a `actionSmallTextStyle` property to use with small buttons (including a default `_kDefaultActionSmallTextStyle` TextStyle)
Preview & example:
> **NOTE**: there is a discrepancy in dark mode button foreground color between the default CupertinoTheme and the HIG. A separate issue will be opened for this.
~EDIT: issue reported here https://github.com/flutter/flutter/issues/152846~

* Can show context menus anywhere in the app, not just on text.
* Unifies all desktop/mobile context menus to go through one class (ContextMenuController).
* All context menus are now just plain widgets that can be fully customized.
* Existing default context menus can be customized and reused.
