meta: Use ARB_explicit_attrib_location in the rest of the meta shaders.
This is cleaner than using glBindAttribLocation().
Not all drivers support the extension, but I don't think those drivers
use GLSL in the first place. Apparently some Meta shaders already use
GL_ARB_explicit_attrib_location, so I think it should be okay.
Honestly, I'm not sure how the old code worked anyway - we bound the
attribute location for "texcoords", while all the shaders capitalized
or spelled it differently.
v2: Convert another instance in brw_meta_fast_clear.c.
