kmsdrm: honor mode previously set by SDL_SetWindowDisplayMode when enabling fullscreen

and remove duplicate SDL_WINDOWEVENT_RESIZED event

commit 2067a7db8e made SDL_SetWindowSize and
SDL_SetWindowFullscreen modify the display mode previously set by a call to
SDL_SetWindowDisplayMode

as far as I understand the SDL API, calling SDL_SetWindowDisplayMode followed
by calling SDL_SetWindowFullscreen(..., SDL_WINDOW_FULLSCREEN) is the correct
way to mode set / switch to fullscreen

this change restores that functionaliy when switching to SDL_WINDOW_FULLSCREEN,
but other cases are still modifying the display mode set by the user. rather
than modifying the display mode set by the user, it seems this logic inside of
KMSDRM_ReconfigureWindow should be pushed further down into KMSDRM_CreateSurfaces
(as it was originally) to only modify the final mode that's set (based on the
fullscreen flags), but not override the mode requested by the user
