The _LIBCPP_PSTL_CUSTOMIZATION_POINT macro was assuming that the policy
was called _RawPolicy and referencing it by name. It happened to always
work but this was definitely accidental and an oversight in the original
implementation. This patch fixes that by passing the policy to the macro
explicitly. Noticed while reviewing #66968.
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 .

We plan to add concepts for checking that iterators actually provide what they claim to. This is to avoid people thinking that these type traits actually check the iterator requirements in more detail.
