[PATCH] D152758: [NFC] Refactor MBB hotness/coldness into MBFI.

Thanks for the follow up. It doesn't feel like this belongs to MBFI either. BFI for IR doesn't contain any of the hotness query - instead these are all part of PSI.

I'm wondering if we can make some template functions in PSI that cover both IR and MIR hotness queries, since BFI and MBFI have very similar APIs. We have precedence for PGO code sharing between IR and MIR (`SampleProfileLoaderBaseImpl<BT>`).
