* Revert "Revert "Add buttons to gestures (#30339)" (#31801)"
This reverts commit 8fd7fa492aaad0d0d4aa062d71b1ecba8b0d4f44.
* Synthesise kPrimaryButton for unknown devices
* Change TestPointer to a better API
## Description
Make `_RenderCustomClip`'s `clipBehavior` non-final so we can update it during `updateRenderObject`. This will support `clipBehavior` changes in hot reload.
## Related Issues
Fixes#30863
## Tests
I added the following tests:
* ClipRect updates clipBehavior in updateRenderObject
* ClipRRect updates clipBehavior in updateRenderObject
* ClipOval updates clipBehavior in updateRenderObject
* ClipPath updates clipBehavior in updateRenderObject
* PhysicalModel updates clipBehavior in updateRenderObject
* PhysicalShape updates clipBehavior in updateRenderObject
- Move `setState` to only be invoked when guarded by `widget._allowMultiplePanelsOpen`, fixing the case for `ExpansionPanelList`
- Remove setting `_currentOpenPanel` to `widget.initialOpenPanelValue` in `didUpdateWidget`, since this should only occur on `initState` and not every time the widget is updated. This fixes the problem for `ExpansionPanelList.radio`
- Added a `didUpdateWidget` condition for when `ExpansionPanelList` changes into `ExpansionPanelList.radio` to open the panel at `widget.initialOpenPanelValue`
- Added test cases for regression, expansionCallback cases, and `didUpdateWidget` transitions between `ExpansionPanelList` and `ExpansionPanelList.radio`
* Callbacks of tap, long press, drag, and double tap GR respond to only primary events.
* Add "secondary" callbacks to tap.
* Recognizers only compete on events if there are any related callbacks.
* Add "kSecondaryButton" constant.
It looks like the documentation for UiKitView has been copy-pasted from AndroidView or so.
This PR fixes the word 'Android' to 'iOS' for the `creationParams`.

This re-lands the Focus changes in #30040. Correctness changes in routes.dart, and removes the automatic requesting of focus on reparent when there is no current focus, which caused undesirable selections.

Adds support for mouse pointer hovering to trigger tooltips, as well as custom timeouts for the tooltip durations, and a custom decoration. It also makes the tooltip be fully opaque when shown, and fade in over 150ms, and fade out over 75ms, and draw a 4.0 corner radius, all to conform with the material spec. Prior to this change, it was using a corner radius of 2.0 when shown, and faded in and out over 200ms.
