[libc++][NFC] Remove _LIBCPP_DISABLE_EXTENSION_WARNINGS (#133693)

Browse Source 
We only use `_LIBCPP_DISABLE_EXTENSION_WARNINGS` in a single place while
we use extensions all over the place. The warnings are already disabled,
since libc++'s headers are system headers, so this shouldn't be in any
way observable by users.
