feat(wm): use device id for monitor index pref

This commit begins to build on some of the knowledge shared by EBNull in
allowing users to specify monitor index preferences using physical
device identifiers. This does not presently go all the way to EDIDs, but
the display model and what I believe is a port identifier on the display
adapter(s) can be used to uniquely identify a display in most use cases.

However, I believe I may have unfortunately run into a bug in either
windows-rs or Rust itself, as when the code calling EnumDisplayDevices
is called, it always fails when running a release build, and always
succeeds when running a debug build. This needs to be investigated
further.
