Fix memory leak with the shared distance field glyph cache.
A new glyph node instance registers its owner element with its
glyph cache which in the case of the shared distance field glyph cache
connects a signal from the cache to a slot on the owner, changing the
text creates a new node but destroying the old node didn't remove the
connection causing them to accumulate over time.
In the glyph node; unregister the owner element from the cache on
destruction, and in the cache only connect an owner element the
first time it is registered and keep a reference count so the
items can be disconnected when registrations from all nodes have
been cancelled.
