Subject: [PATCH] fix(rage-input-five): release the cursor clip when the window
 loses focus

`ClipHostCursor` keeps the last rect it applied and skips the call when it is
asked for the same one again, to avoid the repeated `ClipCursor` calls that
load DWM.

Windows drops the clip by itself when the window stops being the foreground
one, but that cache does not know about it, so when the game asks for the same
rect again after alt tabbing back the call is treated as a duplicate and never
reaches `ClipCursor`. The cursor is then free to leave the window during
gameplay.

Clear the cache on `WM_ACTIVATEAPP` when focus is lost so the game's own
request goes through on the way back in. `rage-input-rdr3` already does this,
from pr-3637.
