Make __resource_adaptor_imp usable with C++17 memory_resource
...
By making the memory_resource base class a template parameter the
__resource_adaptor_imp can be used to adapt an allocator into a
std::pmr::memory_resource instead of experimental::pmr::memory_resource.
* include/experimental/memory_resource: Adjust comments and
whitespace.
(__resource_adaptor_imp): Add second template parameter for type of
memory resource base class.
(memory_resource): Define default constructor, destructor, copy
constructor and copy assignment operator as defaulted.

PR libstdc++/70940 optimize pmr::resource_adaptor for allocators using malloc
...
pmr::resource_adaptor can avoid allocating an oversized buffer and doing
manual alignment within that buffer when the wrapped allocator is known
to always meet the requested alignment. Specifically, if the allocator
is known to use malloc or new directly, then we can call the allocator
directly for any fundamental alignment.
