SDL: Do not reset window size when engines update rendering surface

This change allows:

* Engines to update their target rendering surface/size and pixel
  format with the backend multiple times during gameplay;
* Users to resize the ScummVM window without having it reset
  size/position every time an engine updates its target surface
  format;
* Conversions/scaling to continue to run efficiently in hardware,
  instead of requiring engines to pick their maximum possible
  output format once and upscale inefficiently in software;
* The window to reset size once when an engine calls to set its
  initial output size, and to reset again once ScummVM returns to
  the launcher.

This is relevant for at least SCI32 and DreamWeb engines, which
perform graphics mode switches during games.
