st/entry: Invalidate text shadow on style changes to ClutterText

Browse Source 
We update a few properties of ClutterText when the CSS changes via
_st_set_text_from_style() (which we call when receiving the
style-changed signal).

Right now we simply invalidate the text shadow every time we receive the
style-changed signal, but we're going to change that with the next
commits. To ensure the shadow still gets invalidated on CSS changed that
might affect the shadow, listen to a bunch of property changes that will
get notified when any property that affects the shadow changes.
