Revert of command_buffer_gles2: Add test command_buffer_gles2_test for command_buffer_gles2 (patchset #8 id:140001 of https://codereview.chromium.org/1640243002/ )

Reason for revert:
This seems to not build in release component builds: https://build.chromium.org/p/chromium.fyi/builders/CrWinClang%28shared%29/builds/7700/steps/compile/logs/stdio

Original issue's description:
> command_buffer_gles2: Add test command_buffer_gles2_test for command_buffer_gles2
>
> Add test command_buffer_gles2_test for testing command_buffer_gles2
> library.
>
> Makes the gpu bots to build target, but the target is not run
> on any bot.
>
> As an example, fix a potential nullptr reference in eglInitialize
> and tests the problem.
>
> Adding the test runner would be useful in order to further develop
> command_buffer_gles2. One development direction of the library
> would be to extend it enough to support creating OpenGL ES 3.0
> context.
