Same approach as the other bug, mostly replacing automatically by removing
'using mozilla::Forward;' and then:
s/mozilla::Forward/std::forward/
s/Forward</std::forward</
The only file that required manual fixup was TestTreeTraversal.cpp, which had
a class called TestNodeForward with template parameters :)

When cloning an animated image decoder, we asserted that
Decoder::HasAnimation was true. This is incorrect because if the decoder
has yet to complete the metadata decoding, or it has but only finds out
the image is animated when it discovers the second frame, then we will
try to clone a valid animated image decoder, but fail the assertion.
Instead, this patch verifies the image type supports animations.
When we need to recreate an animated image decoder because it was
discarded, the animation may have progressed beyond the first frame.
Given that later in the patch series we need FrameAnimator to be driving
the decoding more actively, it simplifies its role by making it assume
the initial state of the decoder matches its initial state. Passing in
the currently displayed frame allows the decoder to advance its frame
buffer (and potentially discard unnecessary frames), such that when the
animation actually wants to advance as it normally would, the decoder
state matches what it would have been if it had never been discarded.
If there is an active provider which has yet to produce a frame, any
calls to SurfaceCache::Lookup will return MatchType::PENDING. If
RasterImage::Lookup gets the above result while given FLAG_SYNC_DECODE,
it will attempt to start a new decoder. It is entirely possible that
when we try to insert the new provider into the SurfaceCache, it cannot
because the original provider finally did produce something. In that
case we should abandon attempting to redecode and retry our lookup.
Most cases where the pointer is stored into an already-declared variable can
trivially be changed to MakeNotNull<T*>, as the NotNull raw pointer will end
up in a smart pointer.
In RAII cases, the target type can be specified (e.g.:
`MakeNotNull<RefPtr<imgFrame>>)`), in which case the variable type may just be
`auto`, similar to the common use of MakeUnique.
Except when the target type is a base pointer, in which case it must be
specified in the declaration.

When SurfaceCache::Lookup is called to access surface data, it indicates
that the caller will not accept substitutes as in the case of
SurfaceCache::LookupBestMatch. As such, we need to be careful not to
remove those surfaces from our cache when pruning (in part 8b). This is
the marker used to track that, at some point, there was a caller which
got this surface that would accept no other (e.g. factor of 2 mode must
make an accept for this particular surface).
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.
