Services recycle nodes when gathering possible actions
for users to take. It's very confusing for them if they
can't recycle the node without breaking their ability
to activate a clickable span inside it.
Making ClickableSpans used for accessibility independent
of their parent nodes.
Also adjusting the value used for invalid window ids to
come from AccessibilityWindowInfo. I must have missed this
in an earlier cleanup. I needed the value for the spans,
so I figured I might as well use the correct one.
Bug: 37004527
Test: Now recycling the node in the a11y cts test.
