This CL updates CXFA_Object to have a flag which annotates if the node
is ready. Ready means that we've gone through the OnNodeReady call in
CXFA_FFNotify. Previously we'd check if the WidgetAcc exists on the node
which is created in OnNodeReady.
This CL replaces all the points where we check for a WidgetAcc existing
with a IsWidgetReady() call.

This CL merges the CXFA_WidgetData class into the only subclass,
CXFA_WidgetAcc. Code has been updated as needed.

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.

This CL moves the .h files to have names corresponding to the contained
classes. The .cpp files are moved alongside the .h files. Any extra
classes in the .h files have been split into their own files.
