This patch mainly consists of two parts, one for resolving and the other
for reordering.
In the resolving part, the added code stores the lowest embedding level
of all bidi formatting characters precede a frame to the bidi data of
that frame when necessary.
In the reordering part, virtual frame is restored from the information
stored above before asking the bidi engine to reorder frames
Collapsing a run of continuous virtual formatting characters into one
virtual character with the lowest embedding level among them should work
because a character with a higher embedding level than either of its
neighbors should not affect the reordering result of any other part of
the sequence. (No formal proof of this theorem, though)

This patch is mainly based on smontagu's wip patch. Some non-trivial differences:
* BidiParagraphData.mIsolateCount and related code are not added in this patch.
I investigated uses of this field in the wip patch, and it seems to me none of
them makes sense:
1. in the fast path of nsBidiPresUtils::ResolveParagraph, if there would be
any isolate character in the surrounding text, there must exist more than
one runs, which indicates the isolate count condition is redundant.
2. in handle of br frame in nsBidiPresUtils::TraverseFrames, based on my
understanding of "CSS Writing Modes Level 3" section "2.4.4. Paragraph
Breaks Within Embeddings and Isolates", the resolving should happen
unconditionally.
* {control,override}Char in nsBidiPresUtils::TraverseFrames are assigned
unconditionally when in a bidi inline container, so that we can properly
handle it when there are continuations. I suspect this was the reason of
regressions in dynamic reftests from the wip patch mentioned in comment 1.

If we create an animate SVG along with its parent, in rare cases,
the animation does not start in the first frame, i.e, it's the frame
that the animated element and its parent element are created. In such
cases, restyle for the animation is not observed in the first frame.
To avoid it, we need to create parent element in the first place,
then, append an animated element into the parent in the next frame.

Add a new file, KeyframeEffectParams.h, and define the basic data
members nsString for the spacing mode.
Also, add one more argument, const KeyframeEffectParams&, to the
constructors of KeyframeEffect(ReadOnly).

Before this change, SetupJustificationSpacing calls ComputeJustification
to compute how justification gaps are assigned to characters, and store
them in the PropertyProvider instance. When GetSpacing is called, those
information would be used to compute actual spacings from justification
before/after each character.
The bug is that, GetSpacing did not take gaps before the given range
into account when computing the spacing, which leads to unstable results
when range varies because of ignorance of accumulated error.
This patch changes it to eagerly computing the actual spacings inside
SetupJustificationSpacing, so that GetSpacing just queries the result
from mJustificationSpacings.

Masayuki suggests GetCharcterRectsInRange instead of first idea's API by part 2 implementation.
IME wants to need the width per character. Now nsTextFrame/nsIFrmae has only API to get point of string. So I want to add this method to calculate simply by comment #3.
If no text frame, I would like to return error due to no character. (Caller shouldn't call this API on non-text frame.)
