SF: Remove layer stack lookup for screencap
GPU virtual displays now have IDs, so the (ambiguous) fallback is no
longer necessary.
Remove PhysicalDisplayId constructor from uint64_t to enforce error
checking at compile time when upcasting or deserializing.
Bug: 162612135
Bug: 182939859
Test: screencap -d <id>
Test: DisplayId_test
