This CL splits up BiInterpolImpl into the three interpolations its made of. In
the interpolation, safe math is used, and a boolean keeps track of whether an
overflow has occurred. If it does, we consider the patch to be invalid and
immediately terminate the Draw method.

The Gif module is only using the longjmp as a way to catch errors, so this CL
makes it use GifDecodeStatus::Error instead.

CPDF_PageRenderCache::m_ImageCache is a map from streams to
an image cache entry containing a clump of data associated
with the stream. Oddly, the clump includes the stream key (which
we already have in order to get to the clump), but worse doesn't
ensure the existence of the CPDF_Image object which (maybe) owns
the stream key in question.
So replace the stream with a retained ptr to the image.
Also renamed an unrelated member to avoid confusion with the
CPDF_Object in play.

There are places where an object "child" has a raw pointer
back to object "owner" with the understanding that owner will
always outlive child.
Violating this constraint can lead to use after free, but this
requires finding two paths: one that frees the objects in the
wrong order, and one that uses the object after the free. The
purpose of this patch is to detect the constraint violation
even when the second path is not hit.
We create a template that is used in place of TYPE*. It's dtor,
when a memory tool is present, goes out and probes the first
byte of the object to which it points. Used in "child", this
allows the memory tool to prove that the "owner" is still alive
at the time the child is destroyed, and hence the constraint is
never violated.
