[Xcode] Use different PGO profiles for each architecture
https://bugs.webkit.org/show_bug.cgi?id=312619
rdar://172932216
Reviewed by Alexey Proskuryakov.
Relanding with a env var lookup fix in `copy-profiling-data.py`.
Internal infrastructure now generates per-architecture PGO profiles at
paths like:
./usr/local/include/WebKitAdditions/Profiling/arm64e/JavaScriptCore.profdata.compressed
./usr/local/include/WebKitAdditions/Profiling/x86_64/JavaScriptCore.profdata.compressed
and so on. Update the build system logic that decompresses these
profiles to take active architecture(s) into account.
The architecture-specific profiles will be decompressed to paths like:
WebKitBuild/Release/DerivedSources/JavaScriptCore/Profiling/arm64e.profdata
WebKitBuild/Release/DerivedSources/JavaScriptCore/Profiling/x86_64.profdata
Change the xcconfig logic that computes -fprofile-instr-use flags to
reflect the new input paths.
