  -----------
  [libc++][PSTL] Parallelize random_access_iterator

P2408 requires this for C++23, but implementing it in C++20 is safe
because the only code impacted would be code that violated a
precondition of the parallel algorithm. It was P2408 intent to
enable implementations to backport this to C++20.

Closes #63447 .
