[memprof] Make InstrProfwriter::addMemProfRecord and its friends private (NFC) (#119831)

This patch makes the following functions private:

- InstrProfWriter::addMemProfRecord
- InstrProfWriter::addMemProfFrame
- InstrProfWriter::addMemProfCallStack

These days, we add MemProf profile to the writer context via
addMemProfData.  We no longer add individual items.
