[AMDGPU] Mark S_NOP as having side effects (#65745)
This prevents S_NOP from being rescheduled past other (side-effecting)
instructions, which is useful because it is generally used to introduce
a short delay or to avoid hazards. Currently this only affects MIR tests
because the compiler itself only inserts nops in PostRAHazardRecognizer
which runs after all scheduling.
