Flutter uses `vswhere.exe` to find Visual Studio installations and determine if they satisfy Flutter's requirements. However, `vswhere.exe`'s JSON output is known to contain bad UTF-8. This change ignores bad UTF-8 as long as they affect JSON properties that are either unused, or, used only for display purposes by Flutter.

Fixes: https://github.com/flutter/flutter/issues/102451

Revert "Add ability for `ModalRoutes` to ignore pointers during transitions and do so on `Cupertino` routes (#95757)" (#104520)

This reverts commit 4c0b0be2.

Adds a bit more clarifying documentation to the implementation of the
outputFollowsExit case, and adds tests that verify the behaviour of
stderr, stdout of processes launched via FakeProcessManager.

Specifically:
* Verifies that stderr, stdout are not emitted immediately after process
  exit if outputFollowsExit is true. They must be emitted at least one
  turn through the event loop later.
* Verifies that ProcessResult.stderr, stdout have the type documented
  according to the encoding passted to Process.run/runSync:
  * List<int> if null is passed as the encoding.
  * String (in the default system encoding) if no encoding is specified.
  * String (in the specified encoding) if an encoding is specified.
