LOG: [X86][NewPM] Add Skeleton for X86 Pass Registry (#150573)

This patch adds most of the x86 legacy passes to the pass registry for
the NewPM. This is intended to outline the work that needs to be done to
get them all ported over.

At least two of the dummy function passes (lower-amx-intrinsics,
lower-amx-type) sort of already have NewPM versions, but leaving them as
dummy function passes for now because they need some touch up before
they actually work.
