Complete initializing a GPU video decoder in a GLES2 context

In this patch a ggl::Context is connected to the GpuVideoDecoderHost in the
renderer process. In the GPU process the GpuVideoDecoder is connected to a
gles2::GLES2Decoder.

These changes will be used in the future to switch context before issuing
video decode commands. This is also needed by the GPU process to translate
a client texture ID to a service texture ID in the GPU video decoder.

TEST=none
