Previously bokeh/model/UI events were only allowed to be sent from client to server. This PR allows the other direction, for events where it makes sense. In particular it adds
ClearInput
event that allows to clear the value of input widgets (those were the property or properties reporting input's value are read-only). This will be used in PR #13873 to replace the ad-hoc mechanism implemented in that PR.
