feat(wm): add cmd to id apps that overflow borders

Applications like Spotify and Discord draw over the default invisible
borders of Windows 10, which means that when komorebi is setting their
positions, the offset is always off by the amount of pixels of the
invisible borders on each side.

This commit makes it possible to identify applications that have
overflowing borders so that they can be handled appropriately by the
window manager.

This commit also takes the opportunity to consolidate the tray and multi
window identifiers into a single vector instead of spreading them across
multiple vectors by identifier type.
