This fixes #32525, because it now marks the compositing bits as needing to be recalculated if the mouse tracker changes its idea of whether or not a mouse is attached.

This bug occurred because the test framework was leaking state from one test to the next (the state about whether a mouse pointer was active), and so even though there was a "passing" test when run in order with the other tests in the file, when the test was run individually (or first), it would have failed and caught the bug.

This adds an assert to make sure that after each test there are no simulated mouse pointers connected, and now calls removePointer in all of the tests where this was a problem.

Some parts of the appbundle build process were based on the logic for building
APK packages.  However, these steps (copying to a directory shared by all
build variants, and calculating a SHA) are not necessary for an appbundle.

- Removes SYMROOT from the Generated.xcconfig. Having it causes current
  versions of Xcode to switch the project's build output to "Legacy",
  which causes anything not overridden to use a project-relative build
  directory instead of a shared directory in DerivedData, breaking
  anything with subprojects that it depends on.
  This means that `flutter run` and builds from Xcode will use
  completely different build directories, but that each should be
  internally consistent.
- Moves the FlutterMacOS.framework to $SRCROOT/Flutter. This is
  consistent with the approach we're moving to for all desktop
  platforms, and avoids issues finding it now that SYMROOT doesn't match
  for the two different build modes.

## Description

These will help identify where the matrix starts to get wrong. 

Also fixed `RenderFittexBox` to no longer paint with empty child which previously triggered invalid matrix computations (NaN with dividing by 0). See also https://github.com/flutter/flutter/pull/7489
