Clean up the logic to emit Flat decoration for builtin and non-builtin shader inputs so that we don't emit duplicate Flat decorations.

Fix the legalization logic of array-typed system values to allow emitting correct code for SV_TessFactor and SV_InsideTessFactor for spirv.

Closes #4313. Closes #4315.
