Revert of gpu: Add base class for gpu service tests (https://codereview.chromium.org/332303002/)

Reason for revert:

Original issue's description:
> gpu: Add base class for gpu service tests
> 
> This allows for properly setting up and tearing down GL bindings.
> Before this patch bindings were intialized in unittest_main.cc but also
> reinitialized with a different GL version and extension in some
> GLES2CmdDecoderTests which leaves room for problems depending on which order
> tests happen to run in.
> 
> More importantly, this will allow me to initialize GL bindings with a certain
> GL version and extension bindings for some tests.
> 
> Committed: https://src.chromium.org/viewvc/chrome?view=rev&revision=278059
