Martin Storsjö 3785a413fe Reapply [LLD] [COFF] Implement a GNU/ELF like -wrap option
Add a simple forwarding option in the MinGW frontend, and implement
the private -wrap option in the COFF linker.

The feature in lld-link isn't gated by the -lldmingw option, but
the option is left as a private, undocumented option primarily
used by the MinGW driver.

The implementation is significantly based on the support for --wrap
in the ELF linker, but many small nuance details are different
between the ELF and COFF linkers, ending up with more than a few
implementation differences.

This fixes https://bugs.llvm.org/show_bug.cgi?id=47384.

Differential Revision: https://reviews.llvm.org/D89004

Reapplied with the bitfield member canInline fixed so it doesn't break
builds targeting windows.
