command_buffer: Support instanced path rendering in gpu command buffer

Implement support for instanced path rendering in gpu command buffer.
Exposes following new functions through command buffer:
glStencilFillPathInstancedCHROMIUM
glStencilStrokePathInstancedCHROMIUM
glCoverFillPathInstancedCHROMIUM
glCoverStrokePathInstancedCHROMIUM
glStencilThenCoverFillPathInstancedCHROMIUM
glStencilThenCoverStrokePathInstancedCHROMIUM

These functions are exposed as part of the CHROMIUM_path_rendering
GL ES extension.

Converts the NV_path_rendering functions that Skia calls to these
functions, passes the calls through the command buffer and then
calls the corresponding NV_path_rendering functions.
