Fix frozen screen after exiting vr
When a hotplug connected event occurs, don't recreate any
already-existing entries in mBuiltinDisplays. This fixes a problem where
the screen would freeze after exiting vr.
In the future, we may want to use hotplug connected events to notify
surface flinger to reinitialize display state. This CL includes a change
to the code in HWC2.cpp to always reinitialize the display state when we
get a hotplug connected event, even if the display is already connected.
Bug: 74985350
Test: - Confirmed exiting vr no longer freezes the screen.
- Added code to simulate a hotplug connected event while the device is
running, to test the changes in HWC2.cpp. Confirmed the device
continued to function normally.
