Windows QPA: fix media keys losing autorepeat/keycode information

Browse Source 
For WM_APPCOMMAND messages that also trigger WM_KEYDOWN/WM_KEYUP, let the
latter messages be handled, instead of stripping them and synthesizing a
press/release from the command code, in order to get the correct scan codes
and autorepeat info.

Fixes: QTBUG-73879
