st/icon: Check icon properties for changes before regenerating texture

Properly compare the new icon properties of StIcon to the old ones on
style-changes and only update the icon texture in case something
changed. This should help reduce the amount of texture cache requests
when we start emitting all "style-changed" signals again.
