ProfileData: Introduce InstrProfWriter using the naive text format

Browse Source 
This isn't a format we'll want to write out in practice, but moving it
to the writer library simplifies llvm-profdata and isolates it from
further changes to the format.

This also allows us to update the tests to not rely on the text output
format.
