When building in profile or release mode on desktop, add a prominent
warning that it's actually a debug build. This is to help address issues
with people being unaware of the current state of builds due to
following third-party guides rather than official documentation.

macOS is not included since PRs are in flight for macOS release support.

This reverts commit a11d7314 because of a regression in
flutter_gallery_ios32__transition_perf's 90th_percentile_frame_build_time_millis.

Fixes #38860.

For https://github.com/flutter/flutter/issues/36064

That performance regression is iOS-only so we'd better get the
benchmarks running on iOS.

Flutter widget tests assert if a test completes with timers still
pending.  However, it can be hard to diagnose where a pending timer
came from.  For example, a widget might consume a third-party library
that internally uses a timer.

I added a FakeAsync.pendingTimersDebugInfo getter to quiver
(https://github.com/google/quiver-dart/pull/500).  Make flutter_test
use it.

Additionally modify Flutter's debugPrintStack to take an optional
StackTrace argument instead of always printing StackTrace.current.

Fixes #4237.

* Add ToggleButtons.textStyle property
