[PATCH 0/5] MR5601: Numpad key handling in winewayland.drv (and more generally for drivers using KBDTABLES)

[Alexandros Frantzis (＠afrantzis)]

This MR improves the handling of numpad keys for drivers using KBDTABLES (only the Wayland driver at this point). It achieves this by:
1. Allowing drivers to send only the scancode in keyboard events, with win32u performing the scan->vkey mapping internally. A nice side effect of this change is that it fixes a few user32 input test TODOs.
2. Enhancing wineserver to read extended KBD vkey attributes and perform numpad key mapping depending on modifier state.
3. Providing default VK_NUMPAD* -> WCHAR mappings in win32u.
