Use WS_POPUP for ash_unittests

- Layout test windows starting from (1,1) and move
  mouse to (0,0) so that they don't overlap unless
  test moves the cursor.
- Enabled disabled tests.
- RootWindowHostWin::SetBounds should move the window
  and call OnHostResized when the scale factor has changed.

This also seems to fix the desktop size limitation issue (148691)
probably because a popup window can be larger than the desktop size.
