Move a few more functions from RenderBlock to RenderBlockFlow
https://bugs.webkit.org/show_bug.cgi?id=126494

Reviewed by Andreas Kling.

* rendering/RenderBlock.h:
* rendering/RenderBlockFlow.h:
(WebCore::RenderBlockFlow::adjustInlineDirectionLineBounds):
* rendering/RenderBlockLineLayout.cpp:
(WebCore::RenderBlockFlow::textAlignmentForLine):
(WebCore::RenderBlockFlow::updateLogicalWidthForAlignment):
(WebCore::RenderBlockFlow::startAlignedOffsetForLine):
These are only used by RenderBlockFlow, so move them there.
