  [builtins][AArch32] Fix __gnu_* functions (#137638)

Move to a consistent calling convention for both Clang/GNU such that
they can be linked with each other.

All ARM targets now use the soft-float calling convention for
`__gnu_h2f_ieee` and `__gnu_f2h_ieee`, as described in
https://github.com/ARM-software/abi-aa/blob/main/rtabi32/rtabi32.rst#the-floating-point-helper-functions.
