[LFC][IFC] Move the collapsed bit from InlineItems to runs
https://bugs.webkit.org/show_bug.cgi?id=203183

Reviewed by Antti Koivisto.

Let's not store the collapsed bit on the InlineTextItem. All we need to know is whether the InlineTextItem content is collapsible or not.
Also when only the white-space property changes (going from preserve whitespace to not and vice versa) we don't actually need to rebuild the
InlinItem list since they don't carry any layout dependent information.
This patch also fixes leading/trailing content preservation.
