[lld-macho] Devirtualize TargetInfo::getRelocAttrs
This method is called on each relocation when parsing input files, so
the overhead of using virtual functions ends up being quite large. We
now have a single non-virtual method, which reads from the appropriate
array of relocation attributes set in the TargetInfo constructor.
This change results in a modest 2.3% reduction in link time for
chromium_framework measured on an x86-64 VPS, and 0.7% on an arm64 Mac.
