Instead of checking nsIFrame::IsTextFrame() and then casting to nsTextFrame,
the new code just checks the writing mode of the frame. Less casts; less
chance of pointer errors.

The GetSelection changes are so we have a Selection that we can get an nsRange
from via GetRangeAt, so we can call nsRange::CloneRange.

I got a bit carried away with fixing up consumers to use nsINode... But as a
result removing these methods all together made sense.

Everyone calls them with the shell of the current composed document, and this
allows the multi-presShell stuff to just be in UpdateCurrentStyleSources /
DoGetStyleContextNoFlush.
The only reason we need to use OwnerDoc()->GetShell() instead of the composed
doc in GetStyleContext / GetStyleContextNoFlush is Element::GetBindingURL, which
does expect to get the binding URL for stuff outside of the composed doc (and
changing that gave me a useless browser).
That's technically a behavior change on the cases that used to pass nullptr, but
I think all callers are fine with that. I could also just add a special function
for that particular case, it may be worth it.

This also changes the function to return a sequence (JS Array) instead of
an nsFontFaceList object, and converts nsFontFace/nsIDOMFontFace into a
Web IDL implemented object too.

nsRange::SetStart(), nsRange::SetEnd(), nsRange::IsPointInRange() and
nsRange::ComparePoint() take a set of container node and offset in it to
specifying a DOM point. However, the caller may not have computed the offset
but may know the child node at the point. In such case, they can avoid
computing the offset with nsINode::IndexOf() if they have overloads which
take RawRangeBoundary.
Therefore, this patch implements the overloads and changes the callers in
editor.

EditorDOMPoint was a subclass of RangeBoundary. Therefore, for heavy
use of it in editor, we've implemented a lot of complicated feature
into RangeBoundary. However, EditorDOMPoint stopped inheriting
RangeBoundary. So, we can get simple RangeBoundary implementation
back now.
This patch makes RangeBoundary.h almost same as 3f7cbec2446b except
keeps implementing GetPreviousSiblingOfChildAtOffset() and
GetNextSiblingOfChildAtOffset() because the former is used by
Selection and both of them are simple. And also keeps making it
a friend of EditorDOMPoint because EditorDOMPoint still needs to
copy to/from RangeBoundary.

RangeBoundaryBase shouldn't compute mRef when it's initialized with offset.
E.g., some users of the template class may initialize it with a container and
offset in it but it may not refer mRef or may refer after modifying offset.
On the other hand, RangeBoundaryBase::InvalidateOffset() is a special method.
It assumes that mRef is always initialized when it's called but can be
invalidate mOffset until retrieved actually. This is necessary for
nsRange::mStart and nsRange::mEnd since the offset may be changed when
some nodes are inserted before the referring node.
So, now, InvalidateOffset() should be a protected method and make nsRange a
friend class of RangeBoundaryBase. Then, when nsRange sets mStart and/or mEnd,
nsRange itself should guarantee that their mRefs are initialized.
