[memprof] Move writeMemProf to a separate file (#137051)

This patch moves writeMemProf and its subroutines to a separate file.

The intent is as follows:

- Reduce the size of InstrProfWriter.cpp.
- Move the subroutines to a separate file because they don't interact
  with anything else in InstrProfWriter.cpp.

Remarks:

- The new file is named IndexedMemProfData.cpp without "Writer" in the
  name so that we can move the reader code to this file in the future.
- This patch just moves code without changing the function signatures
  for now.  It might make sense to implement a class encompassing
  "serialize" and "deserialize" methods for IndexedMemProfData, but
  that's left to subsequent patches.
