feat(Hoverer): add delay property and remove hardcoded timeouts

[Kurtil]

Description

The Hoverer component seems laggy because of some hardcoded timeouts in its implementation. I assume it is mainly to debounce too many mouse move events. This PR add the ability to change these timeouts (0 for my use case). The original behavior is not changed as the initial value of the delay property is 100 corresponding to the old values (the first timeout is delay / 2 (originally 50)).
