[blocks-in-inline] Shortcut painting of blocks and inline boxes only content
https://bugs.webkit.org/show_bug.cgi?id=303839
rdar://166145784
Reviewed by Alan Baradlay.
With content like
<span><div>foo</div></span>
we don't need to enter inline painting at all.
* Source/WebCore/layout/integration/inline/LayoutIntegrationInlineContent.h:
(WebCore::LayoutIntegration::InlineContent::hasPaintedInlineLevelBoxes const):
(WebCore::LayoutIntegration::InlineContent::setHasPaintedInlineLevelBoxes):
Track if we have any actual inline content that needs painting.

* Source/WebCore/layout/integration/inline/LayoutIntegrationLineLayout.cpp:
(WebCore::LayoutIntegration::LineLayout::layout):
Also return empty repaint rect in case there is no actual inline content to
paint.
Any block content triggers its own repaints.
(WebCore::LayoutIntegration::LineLayout::paint):
Use simple path for blocks only case.
