Enable `f16` for MIPS

Blocked on https://github.com/rust-lang/compiler-builtins/pull/762

It seems as if `f16` works on MIPS now according to my testing on Rust master with LLVM 20, and I was asked [here](https://github.com/rust-lang/rust/pull/137167#issuecomment-2669387820) 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.
