LOG: [libc++] Add missing xlocale.h include on Apple and FreeBSD (#99689)

The `<locale>` header uses `strtoll_l` and friends which are defined in
`<xlocale.h>` on these platforms. While this works via transitive
includes when modules are disabled, this doesn't work anymore if the
platforms are modularized properly.

(cherry picked from commit a55df237375e98cfc2520d5eb1a23b302ef02ba0)
