  [container-queries] Drop layout containment from container-type
https://bugs.webkit.org/show_bug.cgi?id=277122
<rdar://problem/132549134>

Reviewed by Antti Koivisto.

See w3c/csswg-drafts#10544 and the relevant Blink change https://chromium.googlesource.com/chromium/src/+/e28cd00c20c78b8fd11546d59fd6c82243ce7115

1. Drop layout containment
2. Make sure non-initial container-type establishes independent formatting context
3. Do not block container query evaluation on layout containment (see #1).
