Remove dxwrapper; test scripts focus the game window

The default render size (1835x768) is below Direct3D 7's 2048 limit, so the
D3D7 -> D3D9 wrapper and its device-info workaround are no longer needed.
The game pauses start-up until its window is active; game-input.ps1 now
activates it reliably (Alt + SetForegroundWindow, polled), which dxwrapper
had masked. borderless logs the first failed presents.
