Use a single Float16 ABI. (#51666)
 
Currently, Julia uses 2 different Float16 ABIs, depending on the host compiler used to
compile Julia: either pass as integer, or pass as LLVM's native `half`. Since the runtime
intrinsics are implemented in C using `uint16`, this necessitated conversions around the
runtime functions (`gnu_h2f_ieee`, `truncdfhf2`, etc) that the compiler may emit calls to.

This PR switches to always using the 'native' ABIs that platforms have for Float16,
by removing the conversions around runtime calls, and defining our runtime intrinsics
using the native `_Float16` type. Availability of this type depends on the platform, and
the compiler version, so we also define fallbacks that mimick the platform-specific
calling convention.
