Use newest PGO data for Linux and windows-x86 (#51656)
This data was previously held back because we weren't producing
builds with Linux or windows-x86 but now we are. The Linux builds
now produce only a single profdata file, coreclr.profdata, which
should contain all the profile information for all the libraries in the
runtime.
