[MemProf] Fix the propagation of context/size info after inlining (#164872)
In certain cases the context/size info we use for reporting of hinted
bytes in the LTO link was being dropped when we re-constructed context
tries and memprof metadata after inlining. This only affected cases
where we were using the -memprof-min-percent-max-cold-size option to
only keep that information for the largest cold contexts, and where the
pre-LTO compile did *not* specify -memprof-report-hinted-sizes.
The issue is that we don't have a MaxSize, which is only available
during the profile matching step. Use an existing bool indicating that
we are redoing this from existing metadata to always propagate any
context size metadata in that case.
