SF: Plumb physical display IDs to libgui

This CL replaces ISurfaceComposer::{eDisplayIdMain,eDisplayIdHdmi} with
the stable 64-bit display IDs generated by SF. Note that the 64-bit IDs
fall back to the old values if the HWC API for display identification is
not supported.

Bug: 74619554
Test: LocalDisplayAdapter and Choreographer receive 64-bit IDs
Test: 64-bit IDs fall back to 0 and 1 on HWC 2.2 and below
