Enable f16 for MIPS

Browse source 
It seems as if `f16` works on MIPS now according to my
testing on Rust master with LLVM 20, and I was asked to
create PRs with my changes.

I only tested on the flavour of `mipsel-unknown-linux-gnu`
hardware that happens to be available to me, so I can't say
anything about other MIPS hardware, but from a casual
skimming of the LLVM code ([1], [2]) it seems like `f16`
should work on all MIPS hardware. So enable it for all MIPS
hardware.
