This commit adds a new WindowManagerEvent, LocationChange, which allows
komorebi to listen to and dispatch events to border_manager when
EVENT_OBJECT_LOCATIONCHANGE is emitted by the operating system.

This is required because there is no other event which fires on window
maximize/unmaximize.

fix LGUG2Z#1137

This commit fixes an issue where when trying to move floating windows or
windows on a floating workspace across boundaries to another monitor
using the `move_container_in_direction` it wouldn't move the floating
windows physically, although it moved them internally on komorebi,
resulting in weird and wrong behavior.

This commit creates a new method on `Monitor` to
`add_container_with_direction` which takes a move direction and then
uses the same logic that was previously on the
`move_container_in_direction` function.
It changes the `move_container_to_monitor` function to take an optional
move direction which if it is some will have this function call the new
method `add_container_with_direction` instead of just `add_container`.
Lastly the `move_container_in_direction` function now when it realizes
the move will be across monitors simply calls the
`move_container_to_monitor` with the direction that was initially given
to it.
These changes require that all callers of `move_container_to_monitor`
add an direction option, instead of passing `None` on all of them, a new
helper function was created, named `direction_from_monitor_idx` which
calculates the direction a move will have from the currently focused
monitor and the target monitor return `None` if they are the same or
returning `Some(direction)` if not. This way now all commands that call
a move across monitor will use the logic to check from the direction if
it should add the container on front or end.

Use the same `add_container_with_direction` function on
`move_container_to_workspace` as it is being used on
`move_container_to_monitor` or `move_container_in_direction`.

This way we bring parity between all methods and make it easier to
change the way a container is added on a monitor workspace when taking
the move direction into consideration.
