Wait for system decor windows on all displays during boot

To prevent from showing empty content on some displays temporarily,
wait for displays which support system decorations that have the
expected window types to be drawn.

Also correct the conditions for waiting:
- isVisibleLw and !isDrawnLw are contradicted because they both
  check mHasSurface.
- TYPE_APPLICATION must belong to an activity so it is more
  reasonable to check BASE_APPLICATION.

Test: atest DisplayContentTests \
      #testShouldWaitForSystemDecorWindowsOnBoot_OnSecondaryDisplay
Test: manual enable "Simulate secondary displays" in dev options.
      Reboot and check no "BOOT TIMEOUT" in log.
