MSL: Force disabled fragment builtins to have the right name.

DXVK emits SPIR-V where fragment shader builtins have names derived from
DXBC assembly, e.g. `oDepth` for `FragDepth`. When we declared the
disabled output, we used this name, but when referencing it, we
continued to use the GLSL name. This breaks compilation.
