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.
