[MC][NFC] Use std::map for AddressProbesMap

[aaupov]

AddressProbesMap is keyed by binary addresses, and it makes sense to
treat them as ordered. This also enables slicing by binary function/
binary basic block, to be used in BOLT
(#99554).

Test Plan: NFC

LGTM.

@aaupov this comment doesn't make sense. unordered_map is faster, and it was intentional. Order wasn't needed.

The intention of this patch is only obvious with the other patch that uses the map, so it'd be better to merge the two in one patch.

Sorry, the wording wasn't ideal. I was trying to convey that addresses can be treated as ordered keys (unlike e.g. GUIDs), which allows certain lookups as in the follow-up diff.

I see your point, but I tried to explain the intention in the message. I applied the usual logic of keeping changes small and isolated, but perhaps in this case the changes were best left coupled.
