Polymorphic Allocator Proposal

Design: #129

Depends on #105

Building of off cuda::memory_resource to introduce cuda::polymorphic_allocator-like types

[brycelelbach]

I'd really rather not call it polymorphic. It's a bad name, it's not important for the user to know that, and some classes of performance-sensitive users are allergic to polymorphism even if it's not relevant to performance (as is the case here).

I have no qualms with axing the "polymorphic" part of the name. Would we just call it cuda::allocator and it always works with a memory_resource*?

I'm in favor of cuda::allocator.
