compositor: Keep track of what views were activated by clicking 

Adds a weston_view_activate() that can be passed an additional active
flag WESTON_ACTIVATE_CLICKED, that the shell passes when a view was
activated by clicking.

This allows shell-independent components implement heuristics depending
on how a view was activated.
