Get the latest display info for overlay change 

LocalDisplayAdapter.LocalDisplayDevice#updateDeviceInfoLocked
posts to display thread when receiving onOverlayChanged. So
the operation depends on it should run sequentially.

This partial relands commit 08a30491 to make sure that the display
info can include the latest cutout info after changing the cutout
overlay resources. The reconfigureDisplayLocked in previous commit
is not called in this change because that will require to fix
configuration calculation according to decor windows that provide
display config related insets.

Bug: 222572231
Bug: 240961743
Test: Toggle different types of cutout in developer options,
      the cutout change should be applied immediately on screen.
