Revert of gpu, cmaa: add glApplyScreenSpaceAntialiasingCHROMIUM unittests (patchset #4 id:60001 of https://codereview.chromium.org/2432413003/ )

Reason for revert:
The tests added here are crashing on an assertion on multiple GPU Debug bots. For example:
https://build.chromium.org/p/chromium.gpu/builders/Mac%2010.10%20Retina%20Debug%20%28AMD%29/builds/18115
https://build.chromium.org/p/chromium.gpu/builders/Win7%20Debug%20%28NVIDIA%29/builds/45966

Snippet from the log:
[548:3764:1025/061243:2681579:FATAL:gles2_implementation_impl_autogen.h(606)] Check failed: textures[i] != 0.
