  [IFC][initial letter] Add support for hugging initial letter when baseline is ideographic
https://bugs.webkit.org/show_bug.cgi?id=250305

Reviewed by Antti Koivisto.

In case of ideographic baseline, we use proper ascent/descent (not cap height) to compute
the line box height for initial letter.

* Source/WebCore/layout/formattingContexts/inline/InlineLineBoxBuilder.cpp:
(WebCore::Layout::LineBoxBuilder::adjustInlineBoxHeightsForLineBoxContainIfApplicable):
* Source/WebCore/layout/formattingContexts/inline/InlineLineBuilder.cpp:
(WebCore::Layout::LineBuilder::adjustGeometryForInitialLetterIfNeeded): When we reset line left and introduce clearance the available width should be set back to the initial value as well.
