`std::make_unique<T[]>(size)` always zero-initalizes the array.
C++20 has `std::make_unique_for_overwrite` to avoid that, while
older C++ versions can use the approach applied here.
The new approach only makes 2 read calls and does not do any seeks.
It is also less general and is internal to `art.cpp`, allowing us to
simplify it somewhat.
- Use UiOkDialog() to display all error messages
- Add SDL simple message, and console fallbacks to UiOkDialog()
- Boot graphics early on to facilitate most error messages with build in
gui
- Some more miniwin clean ups
1. TTF no longer crashes on exit.
2. Art failing to load simply isn't rendered instead of crashing in random places.
3. Fixes empty line rendering in ttf_render_wrapped.cpp
4. dx_cleanup is now idempotent.
Makes the code easier to understand.
Also makes building lists easier.
Also fixes focus indicator in SELLOAD_DIALOG (this type of bug is
impossible with the new structs).
