> I did not audit if any other member functions are missing. Adding these is enough for MSVC STL

The following member functions are still missing:
- `from_range_t` constructor (since C++23),
- constructor from `(n, t)`,
- `operator=` from `initializer_list`,
- `insert` taking `(p, n, t)`,
- `insert` taking `(p, il)`,
- `assign_range` (since C++23).

No change requested. I think they can be added in a following-up PR.
