[IFC][Partial layout] Clear caches when damage points to the beginning of the
content
https://bugs.webkit.org/show_bug.cgi?id=271427
<rdar://125184161>
Reviewed by Antti Koivisto.
1. Content (style) gets mutated
2. Damage points to the beginning of the inline content
3. Subsequent layout gets initiated
4. Partial layout gets converted to full
5. Line layout uses stale inline items
Let's clear caches when partial layout is converted to full to make sure we
don't end up with stale inline items.
