Now that BeginPaintBuffer and BeginPaint are both implemented by content client,
I think it makes sense to just merge them into one method. This simplifies the
interface clients have to use.

CapturedPaintState::mTarget is actually a dual draw target to the black and
white draw targets, so this code will have the white draw target cleared black
and then white. This isn't incorrect, it's just wasteful.

UpdateDestinationFrom actually only uses a rect, so it's best to not be

This commit is the guts of the refactoring.
This commit removes rotated content buffer, and moves the necessary
functionality to content client. All content clients now do not inherit from
rotated content buffer, but contain a refptr to a rotated buffer.
For the basic content client, this is a DrawTargetRotatedBuffer.
For the remote content client, this is a RemoteRotatedBuffer.
The double buffered content client contains an additional RemoteRotatedBuffer
for the front buffer.
Each derived class of content client only needs to implement a method to
create its own rotated buffer. The rest is handled by the base content
client. The remote content clients still override some additional methods
to sync buffers and do IPC.

The front buffer for a double buffered content client is really just another
rotated buffer, so it can simplify the code to use the class we just added.
The goal is to have the back and the front buffer using remote rotated buffers,
but this is a good first step.
Note: The front buffer is represented as a Maybe<RemoteRotatedBuffer> in this
commit, but in the future it will be a RefPtr. That can't be done yet, because
rotated buffer can't implement refcounting in addition to compositable client.

UpdateDestinationFrom is a useful method for any rotated buffer. This will be
needed when content clients are no longer rotated buffers.
Note: EnsureBuffer and EnsureBufferOnWhite were moved out of
UpdateDestinationFrom because I'd like to kill those methods, and so the calls
were moved to all users of UpdateDestinationFrom.

Instead of unconditionally pushing and popping clips per display item,
this patch changes things so that for each recursive display list, we
create an ItemClips struct. We push this onto the stack when we enter
the display list, and pop it off at the end. For each display item, we
check to see if the clips would actually change compared to the previous
display item, and only do the pop/repush in that case.

One of the sticky-pos tests was only passing because of two wrongs that
cancelled each other out in the old code. Specifically, instead of
defining a nested clip with the sticky clip as an ancestor, the clip was being
defined with the root ASR as an ancestor. Both resulted in the nested
clip not scrolling with the actual scrolling scrollframe and so the test
was passing.
The new code changes things so that the nested clip is defined with the
actual scrolling scrollframe as the ancestor, causing the reftest to fail.
Fixing the clip ancestry is not hard but it reveals other problems so
so I'm deferring that to a follow-up bug.

Bug 1409442 is tracking a change that will allow scroll layers to have
multiple ancestors. Without that, there are cases we cannot properly
handle, and so we need to ignore a clip in those scenarios. This patch
makes sure we do that instead of crashing.

When display items (such as mask items) push an out-of-band clip, we
can't use clip ids from, or update clip ids into, the cache. We also
need to ensure we take these out-of-band clips into account when
determining the parent for a new clip we are going to define.

Instead of just keeping a count of how many "extra clips" (aka
out-of-band clips) we have pushed, track more complex information for
each clip. In particular, track the display item's normal clip chain, as
well as the clip id of the extra clip that was pushed. This will be
needed to override clip cache information in the next patch.

This code is more straightforward in its recursion than the old code,
and provides a relatively clean way to explicitly pass the desired
parent when defining a new clip or scroll layer.
Refer to the documentation in the patch for more details.
Note that this patch provides the basic recursive algorithm to define
the clips and scroll layers, although it omits some of the complicating
edge cases which will be added in later patches. The new code is not
invoked from anywhere until all the edge case handling has been done.

By using a variant we can keep a single stack of both clips and
scrollframes, rather than two separate stacks. This is important because
we will want to know how the things are interleaved (e.g. if the last
thing that was pushed was a clip or a scrollframe).

The APIs now allow providing the parent clip or scroll info explicitly
instead of having to push it on the stack. For now we just pass
Nothing() to preserve the existing behaviour, so this change is a
