[memprof] Construct MemProfReader with IndexedMemProfData (#117022)

This patch updates a unit test to construct MemProfReader with
IndexedMemProfData, a complete package of MemProf profile.

With this change, nobody in the LLVM codebase is using the
MemProfReader constructor that takes individual components of the
MemProf profile, so this patch deprecates the constructor.
