  [NewPM][CodeGen] Port `regallocfast` to new pass manager (#94426)

This pull request port `regallocfast` to new pass manager. It exposes
the parameter `filter` to handle different register classes for AMDGPU.
IIUC AMDGPU need to allocate different register classes separately so it
need implement its own `--<reg-class>-regalloc`. Now users can use e.g.
`-passe=regallocfast<filter=sgpr>` to allocate specific register class.
The command line option `--regalloc-npm` is still in work progress, plan
to reuse the syntax of passes, e.g. use
`--regalloc-npm=regallocfast<filter=sgpr>,greedy<filter=vgpr>` to
replace `--sgpr-regalloc` and `--vgpr-regalloc`.
