glsl: split gl_CurrentAttribFragMESA into elements

Graphics / Mesa 3D Graphics Library / Mesa - Marek Olšák [amd.com] - 21 January 2021 21:59 UTC

This reduces the constant buffer size by eliminating unused elements because it's no longer a uniform array that the compiler can't split.

This looks silly, but there is no other way because all elements must be globally declared, which means they can't be generated by a loop.
