Update PAL and GC `BitScanForward` to use `__builtin_clz` (#89350)

The existing PAL code was using `__builtin_clzl` which is intended for platforms
where `long` is 64 bits. Instead use `__builtin_clz`.

The GC version had a similar issue so I've changed that too. The JIT version
was already using `__builtin_clz`.

Fixes #89340.
