Generate GrGLInterface and GrGlAssembleInterface* from table
This CL creates a go program that takes a JSON file of
GPU functions and creates the assemble and validate code
based on that.
This approach will hopefully will lessen the need for
"shotgun surgery" anytime a new function/extensions is added.
Additionally, it should be easier to add a new standard
(concretely, WebGL) using this technique.
There are a few potential bugs/mismatches in the current
implementation that this has identified, for example,
Requiring GL 3.x for adding a feature, but only verifying
it is there on GL 4.x - I did not attempt to correct these
bugs in the old version, as we will hopefully be able to delete
that version and use the generated files.
