Niels Lohmann c60a0bc336 Allocate the deep copy's key scratch space with the provided allocator (#5573)
* Allocate the deep copy's key scratch space with the provided allocator

The iterative deep copy builds each object's keys in a temporary vector of
key/value pairs before handing them to the object's range constructor. That
vector holds basic_json values, so like the values themselves it now uses
AllocatorType instead of std::allocator.

Also document that AllocatorType covers the JSON values, while most
temporary storage still uses std::allocator.

* Count allocate_at_least in the scratch-counting test allocator

From C++23 on, libc++'s containers allocate through allocate_at_least when
the allocator has one. The test allocator inherited it from std::allocator,
so the scratch allocations were not counted and the test failed on Xcode.
