Reland "[A11y] Avoid queuing up a deferred update for every attached node."

This is a reland of commit de68001bf80113d11ff879405c41070b01602902

Reverted in CL:531819. Reason for revert: bug 326386227, failing All/DumpAccessibilityTreeTest.AccessibilityTableHeadersRowRoleDynamic/blink
Fix for test: restore the code that updates roles of <th> cells when sibling cells change.

Original change's description:
> [A11y] Avoid queuing up a deferred update for every attached node.
>
> This is a performance improvement that does not affect behavior.
>
> In many cases when a node is attached, there is no need to queue up
> work for later. Only queue deferred processing when needed.
> Note that ChildrenChanged() is called in many cases where there
> was already an AXObject, but these are deduped via
> nodes_with_pending_children_changed_.
