nptl: Use FUTEX_LOCK_PI2 when available
This patch uses the new futex PI operation provided by Linux v5.14
when it is required.
The futex_lock_pi64() is moved to futex-internal.c (since it used on
two different places and its code size might be large depending of the
kernel configuration) and clockid is added as an argument.
