  [CodeGen] Port PrintMIR to new pass manager (#79440)

The legacy version print machine functions to a string stream, then
output the module and string in `doFinalization`. This patch break
`MIRPrintingPass` into two parts `PrintMIRPreparePass` and
`PrintMIRPass`. `PrintMIRPreparePass` output the original IR in yaml
string, `PrintMIRPass` just print the machine function, so we can avoid
the `doFinalization`.
