[WebAssembly] support f{min, max}imum.f128 and f{min, max}imumnum.f128 (#207160) 
fixes https://github.com/llvm/llvm-project/issues/207100

As far as I can see `wasi-libc` does not currently export the dedicated
libcalls, so I went with a custom expansion. It emits more code, but
will work without any linker errors etc.

The `long double` type is actually `f128` for webassembly, so at least
the libcalls should work.
