rustc_target: add n64 musl targets for MIPS64 arches

Browse source 
Hard-float (unlike mips32 musl targets but consistent with any other
musl target), MIPS64r2, n64 ABI.

The triples are renamed to carry the `abi64` ABI suffix found on all
other MIPS64 targets, for consistency and forward compatibility, should
Rust gain support for the n32 ABI one day.
