This CL enables the framework to manage an arbitrary number of physical displays. It also surfaces physical display IDs, which are stable across reboots and encode (model, port) information that will be propagated further up in a follow-up CL. Bug: 116025192 Test: Boot with more than two displays Test: Hotplug works with any number of displays Test: Verify stable display IDs with "dumpsys display" Change-Id: Idb2eaff66b2e0873be6ad27d337ff18b730d1331
