Backport of #91425 to release/8.0

Customer Impact
Various SOS commands don't work well when loading a Linux arm64/arm32 dump on Windows. clrstack/pe don't display any function names.
The precode code was incorrectly using the HOST_ARM64, HOST_ARM, etc. defines instead of the TARGET_ ones. This means the cross-DAC was using the wrong architectures *Precode::Type codes.
Our vendors have been reporting this issue during their regular SOS testing for too long.
