Reviewed by Simon Fraser.

This patch aligns WebKit with Gecko / Firefox and Blink / Chromium.

Merge: https://chromium.googlesource.com/chromium/src.git/+/545b2183e1b4ee3eb433537f9a6386b5337d6588

RenderReplaced has a m_intrinsicSize that's updated when computing
logical widths and heights (and only if needed; specified style makes
it not being set at all).

But m_intrinsicSize can be used earlier that that, when computing
preferred widths for the container, see
RenderReplaced::computeIntrinsicLogicalWidths called from
RenderReplaced::computePreferredLogicalWidths().

This patch computes the intrinsic size in the constructor to avoid
returning the stale default size.

* Source/WebCore/rendering/svg/LegacyRenderSVGRoot.cpp:
(1) Add constants for 'defaultWidth' and 'defaultHeight'
(2) Add 'intrinsicSize' logic
(3) Introduce new function 'calculateIntrinsicSize'
(LegacyRenderSVGRoot::computeIntrinsicRatioInformation): Call above function and remove unneeded comments
* Source/WebCore/rendering/svg/LegacyRenderSVGRoot.h: Definition of 'calculateIntrinsicSize'
* Source/WebCore/rendering/svg/RenderSVGRoot.cpp: Same changes as 'Legacy' for LBSE
* Source/WebCore/rendering/svg/RenderSVGRoot.h: Ditto
* LayoutTests/svg/in-html/inside-inline-block.html: Add Test Case
* LayoutTests/svg/in-html/inside-inline-block-expected.html: Add Test Case Expectation
