Add Ability to pass in allowed extensions to GPU contexts.

Questions:

1) Is WebGraphicsContext3D only used for WebGL? Currently
this patch makes that assumption.

2) I started by adding const char* allowed_extensions to
a bunch of functions. Then, at the IPC level added
GPUInitParams. Should I use GPUInitParams everywhere?

3) Is the path for gpu_init_params.h ok?

TEST=unit tests, manually tested WebGL
BUG=none
