Address @mclows offline comments

1. I added the `polymorphic_allocator<T>::max_size()` function.
2. `polymorphic_allocator<T>::allocate(size)` now throws `bad_alloc` when `size > size_type(~0) / sizeof(T)`.
3. `polymorphic_allocator<T>::deallocate(ptr, size)` checks size is valid using `_LIBCPP_ASSERT`.
4. `resource_adaptor<A>::do_allocate(bytes)` now throws `bad_alloc` when `bytes > size_type(~0) - alignof(max_align_t)`.
5. `resource_adaptor<A>::do_deallocate(ptr, bytes)` checks that `bytes` is valid using `_LIBCPP_ASSERT`.
