John Scipione 3ef6915cf3 IK: Propagate B_WORKSPACE_ACTIVATED to child views
... and B_WORKSPACES_CHANGED too.

hrev50148 propagated B_SCREEN_CHANGED messages to
children allowing them to respond to screen changes
fixing #8035 back in 2016.

This does the same thing for workspace messages only
I spelled propagate correctly this time.

Add private _PropagateMessageToChildViews() convinience
method to BWindow to do this work.

Call PostMessage() instead of calling MessageReceived()
directly which can work better in certain circumstances.
