The type is known where we need it, and we avoid some dubious
casts in the process. Also avoid clumsy indexing and use the
members directly in computations.

Under XFA, the Form Fill Environment already has the XFA context, so
there is no need for callers to obtain it and pass it.
Tidy some duplicate string allocations along the way.

Should FPDFDocumentFromCPDFDocument() be called several times under
XFA, we may WrapUnique() the document several times. So cache a pointer
back from CPDF_Document to CPDFXFA_Context to avoid this.
Because of layering, introduce a placeholder type CPDF_Document::Extension.
This is actually the first step in some larger XFA ownership cleanup, but
makes a nice standalone CL around the one particular issue.

The timer resets when it moves, and the current starting state is
not visible, so moving the caret around using keyboard keys,
typing, the mouse, or switching focus has a 0.6s delay in showing
its position.

GIF extensions are laid out as follows: <size byte> <chunk of data>
<size byte> <chunk of data> ... <terminator byte>. The decoder needs
to scan along the data, finding the size bytes to determine where
the block ends in the stream, even if we don't care about the
content. Currently the decoder is storing all of the data chunks,
which are never used and take a lot of time to concat together if
they are very small.
Our implementation of the GIF spec does not handle this extension, so
when scanning for the end of the block, just don't bother storing
data from it.

The current implementation of this class potentially does a lot of
work in the constructor. Specifically when getting a calendar font it
might cause the whole font loading pipeline to run. This can fail if
it is unable to load fonts.
Breaking out the font loading part, so that the factory method can
return nullptr if it fails. Additionally adding a guard for the case
the font manager fails to load, which is the root cause of the crash
in the bug.
