Aliaksandr Kalenik efbefb3b59 LibWeb: Skip display list commands under zero-area clips ...

Add a pre-computed `has_empty_effective_clip` flag on
AccumulatedVisualContext that propagates from parent to child. When a
clip rect or clip path has zero area, all descendant commands are
skipped at display list recording time in `DisplayList::append()`,
so they are never stored or executed.

This allows skipping ~10% of display list commands in the Discord app.
