feat(wm): add alt-tab heuristics to wsr

This commit adds some rough heuristics to workspace_reconciliator which
should help with having the correct window focused after reconciliation
in the majority of, but probably not all, cases.

EnumWindows generally returns HWNDs according to z order, and a window
selected by alt-tab will almost always be put on the top of the z order.
Before sending a workspace_reconciliator::Notification, we store this
HWND along with an Instant and an AtomicBool telling us that we have a
candidate to focus after the workspace switch.
