39bc101e82 MSL: Handle the SamplePosition builtin.
This is somewhat tricky, because in MSL this value is obtained through a
function, `get_sample_position()`. Since the call expression is an
rvalue, it can't be passed by reference, so functions get a copy
instead.

This was the last piece preventing us from turning on sample-rate
shading support in MoltenVK.
