[M117 mini] Use simple approach to invalidating aria-hidden subtrees

A general optimization for Chrome was landed in CL:4687538, which
invalidated cached values individual nodes rather than the entire
document, for small changes and updates to the layout and DOM.

However, aria-hidden changes require entire subtrees to be invalidated.
There are a couple of approaches that could work. The one taken
in the landing of CL:4687538 was to attempt to iterate the tree
while invalidating the objects. However, this led to an infinite
loop as invalidating cached objects affects tree walking.

A simpler approach is to reuse another method that works well,
RemoveSubtreeWhenSafe(). This wipes out the entire aria-hidden
subtree of AXObjects and recreates it. As aria-hidden is not
expected to change very often, this is believed to be performant
enough. In addition, this results in being able to remove
InvalidateCachedValuesOnSubtree() from the codebase, resulting
in simpler, cleaner code.
