They should have been taking a PointerDownEvent.

This change was originally included in #81884, but that
had to be reverted because it broke Google testss. This
sub-part of that larger change needs to be made first in
order to allow for a phased rollout in a way that won't
break Google tests.

https://github.com/flutter/flutter/issues/81883

This reverts commit e88a387b.

* Gesture recognizer cleanup

1) Make OneSequenceGestureRecognizer.addAllowedPointer()
   call startTrackingPointer(), and change subclasses to
   call super.addAllowedPointer() in place of manually
   calling startTrackingPointer().
2) Fix addAllowedPointer overrides to take PointerDownEvent
   where some were taking PointerEvent.
3) Add API documentation to OneSequenceGestureRecognizer
4) Make the following fields in OneSequenceGestureRecognizer
   private with public getters instead of publicly writable:
   `state`, `primaryPointer`, and `initialPosition`.
5) Clean up gesture recognizer state in
   OneSequenceGestureRecognizer.didStopTrackingLastPointer.

Fixes #81883

This reverts commit 4a720313.

Depending on the user's build configuration, we may output
multi-architecture or single-architecture binaries. Prefer to install
the multi-architecture binary if built, otherwise fall back to the
single-architecture binary.

This eliminates the use of the Install.ps1 script during Windows app
installation and instead uses uwptool install. Install.ps1 was the
slowest part of app install, and had resource contention issues that
frequently caused it to fail.
