Use LocalStyleChange for element cursor changes in SVG.
Propagating the change to the computed cursor property value through
inheritance is handled correctly when using LocalStyleChange. No need to
force a recalc of the whole subtree.
This is part of making sure non of our SubtreeStyleChanges rely on sibling
tree invalidations, and removing unnecessary use of SubtreeStyleChange, so
that we can make SubtreeStyleChange mean subtree only, and not have to
consider the sibling forest.
