Introduce GLStubApi
The mock GL bindings are useful, but they are very complex to setup and use
(gmock), and too slow for some uses (e.g. a fuzzer), and painful to maintain as
the decoder code evolves.
This CL introduces a GLStubApi as an alternative:
- GLStubApi hooks at the GLApi level rather than the DriverGL level, that is, it
implements a full interface rather than individual functions looked up through
GetProcAddress. It is simpler to override.
- the CL implements an auto-generated GLStubApiBase which only has trivial
functions, as well as a more concrete GLStubApi that implements enough to
initialize and run a GLES2Decoder.
- GpuChannelTest was changed to use the GLStubApi
