Instead of starting transitions and animations as a result of a paint,
use the refresh driver tick to do this.
This sets the transition-ready time to the current time during the next
refresh driver tick that it was started on (see mSawTickWhilePending).
This is similar to what's described in the bugs comments, and seems to
work nicely in practice.
We could easily change that (current time) by a paint-based time if
needed (when available), which would be more similar to what we were
doing. But I'd rather do the simple thing for now, and land this shortly
after the soft freeze is over so that we have time to watch out for
regressions.
There's one regression on a test that birtles wrote (using an XHR doc
and switching the timeline to a rendered doc's timeline).
We use the timeline's document rather than the target document to
determine whether to trigger animations now. That's one of the cases
where we'd keep vsync perma-running without this patch, and Chrome also
fails that test. Maybe the test should be removed / the spec should be
tweaked to allow this behavior?
This causes some progression in some CSS transitions tests too, and I
added an extra test for the vsync behavior.
Over-all this is much simpler to reason about and I think we should try
to do this.

- Use LengthPercentage as the return type for GetIntrinsicHeight and
GetIntrinsicWidth. This allows the caller to handle percent values.
No callers have additional logic to handle percent values as of now,
but this may change in the future, for compat; see last paragraph of
bug 700533 comment 69.
- Refactor intrinsic size function definitions.

All its members are optional, so we can just use it as a plain struct
rather than Maybe<> all around, which simplifies the code and prevents
silly bugs like bug 1779592.
Mostly automatic via:
rg -l 'SVGImageContext' . | xargs sed -i 's/Maybe<SVGImageContext>/SVGImageContext/g'
With trivial build fixes.
Not intended to change behavior.

We'll probably want to do something more accurate in the future with a
custom clang static analysis pass which validates that XPIDL interfaces
have the expected vtable and struct layout, however doing so would be
more involved than the string matching done in this patch.
In addition to checking for extra virtual methods, we'll likely also
want to check for data members on interfaces, and reject them unless the
class is marked as `[builtinclass]` in addition to some other attribute
which we'll need to add to prevent them from being implemented in Rust
(as c++ data members will not be reflected by the rust macro).
There were 2 instances of a comment which contained the word 'virtual'
within a CDATA block. These comments were moved out of the CDATA block
to avoid triggering the error.

We're checking animation consumers, not locked status. We don't care
about animation consumer count of non-animated images.

If we are shutting down, the document for a VectorImage may be cleared.
If a refresh tick raced with the shutdown, we might try to deref the
null document.

In later parts in this series, GetImageProvider will replace
GetImageContainerAtSize. This will be a more specialized and lower

This avoids using D2D when creating a cached SVG image.
We can still hit D2D if we're not caching, but that should
be less common.
