With the conversion of internal string sizes to size_t, these wrappers
are no longer needed. Replacing them with strlen and wcslen

This CL moves the font source into the font manager so it doesn't need
to be stored by each caller (and removes the platform dependant code).
The |EnumFonts| method is exposed on the CFGAS_FontMgr so the caller can
clear the manager if the enumeration fails.

The Find and ReverseFind methods for WideString, WideStringC,
ByteString, and ByteStringC have been converted from returning a raw
FX_STRSIZE, to returning Optional<FX_STRSIZE>, so that success/failure
can be indicated without using FX_STRNPOS.
This allows for removing FX_STRNPOS and by association makes the
conversion of FX_STRSIZE to size_t easier, since it forces checking
the return value of Find to be explictly done as well as taking the
error value out of the range of FX_STRSIZE.
New Contains methods have been added for cases where the success or
failure is all the call site to Find cared about, and the actual
position was ignored.

Currently Find() and other methods that return a FX_STRSIZE return -1
to indicate error/failure. This means that there is a lot of magic
numbers and magic checks floating around. The standard library for
similar operations uses a npos constant. This CL implements
FX_STRNPOS, and replaces usages of magic number checking. It also does
some type cleanup along the way where it was obvious that FX_STRSIZE
should be being used.
Removing the magic numbers should make eventually changing FX_STRSIZE
to be unsigned easier in the future.

CFGAS_GEFonts are ref counted, and its a good thing since they
are managed by at least three different font managers:
CFGAS_FontMgr, CXFA_PDFFontMgr, and CXFA_FontMgr. None of these
have a clear claim to ownership of the CFGAS_GEFont.
CFGAS_GEFont has back-pointers to two of these, CFGAS_FontMgr, and
CXFA_PDFFontMgr, and they could each outlive the other. Thus the
font needs to watch for destruction of either of its managers, so
as to stop using it after its gone.

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.

It's a ref-counted class, so if we're in the destructor, the ref
count has hit zero. We can't make a new ref pointer to itself here,
as it will re-invoke the destructor when it goes out of scope. This
should have been an obvious anti-pattern in hindsight.
The object in question can't be in the m_pFontManager, since the font
manager retains a reference, and we wouldn't get to this destructor
while that is present. So the cleanup isn't required.
Fixing this revealed a free-delete mismatch in cxfa_textlayout.cpp.
I also converted to use unique_ptrs in a few places near this issue.
Fixing this revealed a UAF in CFGAS_GEFont, memcpy'ing a RetainPtr
is not a good idea as it doesn't bump the ref count.
Also protect and friend the CFGAS_GEFont destructor, to make sure
random deletes don't happen.
Also kill off a const cast, and remove unnecessary conversion to
retain_ptr when we already have one.
TEST=look for absence of -11 in XFA corpus test logs, bots not
currently noticing the segv. Argh.
