Symptoms

Game's movie player relies on recent bit in GetAsyncKeyState to detect keypresses (e.g. if ((GetAsyncKeyState(VK_ESCAPE) & 1) != 0)) and these proton hacks interferes so movies cannot be skipped or paused:
4b7342236aedf9db88dcdebd251889262a93505f -> HACK: user32: Always pretend that GetAsyncKeyState recent bit is 0
c8355ba22826e2e492059b7d6eba729f7e3e1256 -> HACK: win32u: Enable GetAsyncKeyState() recent bit for Amerzone (1999).

Reproduction

1. Start the game
2. Try to skip any intro movies (or movie on new game) with Escape key or pause them with Spacebar key.

Start in dlls/win32u/input.c at NtUserGetAsyncKeyState and review the existing game-specific handling for GetAsyncKeyState. Reproduce the issue by trying to skip or pause the intro movies in Dungeon Lords Steam Edition, then verify that the relevant keypress behavior works without regressing the existing case.
