LGUG2Z 8bf4ab9f15 fix(wm): remove blocking channel send calls ...

This commit is the result of a long investigation with @berknam on
Discord which uncovered that when the channels used by the *_manager
modules are full, the window manager can enter a completely locked state
which will require a hard restart of komorebi.exe.

In order to avoid entering this locked state, *_manager modules now no
longer publicly expose event_tx for sending notifications.

Instead, a new public fn send_notification is exposed which will use
try_send to attempt to send notifications in a non-blocking manner and
log warnings if the channel is full and the notification is dropped.
