Add reflection support for GLSL thread-group-size modifier

Fixes #15

These are the modifiers like:

    layout(local_size_x = 16) in;

Unlike the HLSL case, these don't get attache to the entry point function itself, so there is a bit more work involed in looking them up.

Just to make sure I didn't mess up the HLSL case, I went ahead and added two tests for this capability: one for GLSL and one for HLSL.
