Reland "ui: Refactor stable ID generation for GPU virtual displays"
This is a partial port of ag/17832464 for main with additional tests.
Use ftl::stable_hash to generate stable ID from uniqueId for GPU virtual
displays. This allows FLAG_STABLE consistent with PhysicalDisplayId that
uses a unique EDID, as well as being stable across reboots when using
hardcoded or static unique ID.
Add DisplayId.isStable()/isVirtual() interfaces and refactor previous
legacy usages.
