  [PowerPC] Retire PPCExpandISel pass (#84289)

We can decide whether to expand isel or not in instruction selection
pass and early-if-conversion pass. The transformation implemented in
PPCExpandISel can be retired considering PPC backend doesn't generate
`isel` instructions post-RA.
Also if we are seeking performant branch-or-isel decision, we can turn
to selectoptimize pass.
