Unified invalidation for repaint-only style changes (non-layers)

Unified invalidation for repaint-only style changes (non-layers)

Use setShouldDoFullPaintInvalidation() for repaint-only style change
to avoid paintInvalidationForWholeRenderer() on repaint-only style
change.

BUG=394004
TEST=existing layout tests. Some previous duplicated repaints combined.

This is great! Look at all those duplicated invalidations going away :)

LGTM.
