[libc][math] should `asin` functions set `errno == ERANGE` on underflow?

[Flandini]

Following up on #61092.

asinf is setting FE_UNDERFLOW in these cases, but I don't think it sets errno == ERANGE in all cases for all asin implementations. It is implementation defined if errno is set to ERANGE in this case.

Thoughts @michaelrj-google @nickdesaulniers?

I think we should.
