Add CommitOverlayPlanesCHROMIUM command buffer function

This extension is for displaying overlay planes without swapping the
framebuffer. This is useful when overlays account for all the damage and
it would be more efficient to not swap.

This patch is the result of adding the command to
cmd_buffer_functions.txt and build_gles2_cmd_buffer.py and running the
latter. The implementations will be added in a following CL.
