[memprof] Remove verifyIndexedMemProfRecord and verifyFunctionProfileData

This patch removes two functions to verify the consistency between:

- IndexedAllocationInfo::CallStack
- IndexedAllocationInfo::CSId

Now that MemProf format Version 1 has been removed,
IndexedAllocationInfo::CallStack doesn't participate in either
serialization or deserialization, so we don't care about the
consistency between the two fields in IndexAllocationInfo.

Subsequent patches will remove uses of the old field and eventually
remove the field.
