[AMDGPU] Add MachinePipeliner support for AMDGPU

Implement the target hooks to enable MachinePipeliner for AMDGPU. The
pass is off by default and can be enabled with -amdgpu-enable-pipeliner
at -O2 and above.

Only uniform, single-basic-block counted loops with a scalar (SCC)
back-edge are pipelined; loops with a divergent (VCC/EXEC) back-edge, or
containing calls or inline asm, are rejected. Code is generated by the
default modulo schedule expander (DFA, window scheduler, and MVE
expansion are disabled for AMDGPU).

Validated on gfx942 and gfx950 with Composable Kernel and Triton workloads.
