  [IFC][Invalidation] Decouple inline formatting root and inline-level box 
invalidation
https://bugs.webkit.org/show_bug.cgi?id=273020

Reviewed by Antti Koivisto.

Add support for fine-grain invalidation when style changes depending on whether 
the current box is the root
of an inline formatting context or participates in inline layout (could be both 
e.g. inline-block).

e.g. unicode-bidi should be checked on both root and inline-box but going from 
inflow to out-of-flow should
only invalidate inline item caching when the box participates in inline layout 
(i.e. not when root's position value changes)
