[JSC] Use _Float16 only on ARM64
https://bugs.webkit.org/show_bug.cgi?id=277972
rdar://133706761
Reviewed by Mark Lam.
x64 Float16 implementation is subpar compared to ARM64 because of lack of CPU
instructions.
And given that various issues around rt library, just using our C++
implementation would be better for x64.
We use `_Float16` only for ARM64, which has FP16 instructions, in particular on
Apple platforms.
