This change takes the full list of bfd targets that lld supports (see `ScriptParser.cpp`), including generic handling for `*-freebsd` targets (which uses the same settings but with a FreeBSD OSABI). In particular this adds mips support for `--output-target` (but not yet via `--binary-architecture`).

lld and llvm-objcopy use their own different custom data structures, so I'd prefer to check this in as-is (add support directly in llvm-objcopy, including all the test coverage) and do a separate NFC patch(s) that consolidate the two by putting this mapping into libobject.
