This is essentially a reland of https://github.com/flutter/engine/pull/30264/, except that it only applies the opacity if the new alpha (alpha = 255*opacity, where opacity∈[0,1]) is different from the current alpha. Also adds a new opacity screenshot test. Need to figure out how to bring up a new screenshot test... does the screenshot get uploaded automatically? Do I need to manually upload somewhere?

Automated Flutter integration test suites
Each suite consists of either a complete Flutter app and a flutter_driver
specification that drives tests from the UI, or a native app that is meant to
integrate with Flutter for testing.
Intended for use with devicelab tests.
If you want to run a driver test locally, to debug a problem with a test, you can use this command from the appropriate subdirectory:
flutter drive -t <test> --driver <driver>
For example:
flutter drive -t lib/keyboard_resize.dart --driver test_driver/keyboard_resize_test.dart
New tests require new CI runner
Adding code to this directory will not automatically cause it to be run by any already existing ci tooling. This directory is intentinally a "choose your own adventure" piece of tooling.
