Hans-Kristian Arntzen 0909975655 MSL: Declare gl_WorkGroupSize constant with [[maybe_unused]].
Avoids ugly warnings on nearly every compute shader.
We could do analysis to detect whether we need to emit this constant,
but it's a bit tedious to figure out if an OpConstantComponent is
actually used by opcodes, so just make it simple.
