This patch does the following: - Updates `flutter_tester` to set up an Impeller rendering context and surface if `--enable-impeller` is set to true, using the Vulkan backend with Swiftshader. - Updates `run_tests.py` to run all tests except the smoke test (that one really has no rendering impact whatsoever) with and without `--enable-impeller`. - Updates a few tests to work that were trivial: - A couple tests needed updated goldens for very minor rendering differences. Filed https://github.com/flutter/flutter/issues/135684 to track using Skia gold for this instead. - Disabled SKP screenshotting if Impeller is enabled, and updated the test checking that to verify an error is thrown if an SKP is requested. - The Dart GPU based test now asserts that the gpu context is available if Impeller is enabled, and does not deadlock if run in a single threaded mode. - We were missing some trace events around `Canvas::SaveLayer` for Impeller as compared to Skia. - A couple other tests had strict checks about exception messages that are slightly different between Skia and Impeller. - I've filed bugs for other tests that may require a little more work, and skipped them for now. For FragmentProgram on Vulkan I reused an existing bug. This is part of my attempt to address https://github.com/flutter/flutter/issues/135693, although @chinmaygarde and I had slightly different ideas about how to do this. The goals here are: - Run the Dart unit tests we already have with Impeller enabled. - Enable running more of the framework tests (including gold tests) with Impeller enabled. - Run all of these tests via public `dart:ui` API rather than mucking around in C++ internals in the engine.
