  Message : Refactor end2end test macros This is a foundational CL to enabling the end2end tests on swiftshader. Refactored infrastructure with new ANGLE_INSTANTIATE_TEST_ES* macros that will run tests over all various combinations of all platforms for different ES versions. Just skipping failing tests initially to get the refactor landed. Bug: angleproject:4081 Bug: angleproject:4092 Change-Id: I017f6c3267179e49b6ae08cc7488096b423dcdb5 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1904635 Commit-Queue: Tobin Ehlis <tobine@google.com> Reviewed-by: Courtney Goeltzenleuchter <courtneygo@google.com>
