Use __builtin_ctzg and __builtin_clzg in the implementations of
CountTrailingZeroesNonzero16 and CountLeadingZeroes16 when they are
available.
GCC 14 and Clang 19 adds these new builtins. The g-suffix is for
"generic". The s-suffix on __builtin_ctzs and __builtin_clzs is for
"short". GCC never implemented the short versions and #1664 reports
GCC 14 (pre-release) gives an error here, although this may be a
pre-release bug.
Fixes #1664
