LWG3506 Missing allocator-extended constructors for priority_queue

[ben-craig]

Issue: https://cplusplus.github.io/LWG/issue3506
Minutes: None

LEWG should confirm that it is OK with the suggested change. Adding new constructors (and altering overload sets) definitely strays into design territory, but the LWG consensus is that this is just fixing the class to meet the agreed design (namely that each constructor of an allocator-aware type has an allocator-extended twin, taking the same arguments plus an allocator). Even if LEWG is fine with the change, please go over the issue, so that the group is aware of that agreed design, and more likely to ensure future additions to the library follow that design correctly.
