In https://codereview.chromium.org/2559903002 we refactored the font manager
in XFA but got part of the negation wrong. Fixup logic.

Doing so reveals places where there are needless copies

This Cl updates the code to use the constructors instead of creating an
empty object and calling Set(). It also removes the various memsets of
the CFX_Rect{F} classes.

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.

We can remove a lot of "bOwnsStream" logic in the process.
Always pass these by const reference, in case the called method
wants to hang on to the stream (one exception is where we stick
a raw pointer into a void* slot in a context from another layer).

IFGAS_FontMgr is an interface only for a class only defined on Windows,
plus a class only defined for non-Windows. I'm removing the interface,
renaming the class to have the same name in both cases, and cleaning up

Reland of Fix leaked internal font (patchset #2 id:60001 of
https://codereview.chromium.org/2297303004/ )
In CFGAS_FontMgrImp::LoadFont(), a new internal font is created which
is never released. It needs to be correctly marked as internal font to
be released. Fix this by adding a new method to take the ownership
of the font and mark it as internal font properly.
The previous revert was caused by memory management errors
which were fixed at https://codereview.chromium.org/2322043002/

A few issues are fixed:
--Change variable |m_bLogic| in CFX_Font to |m_bShallowCopy| to
reflect its meaning better;
--For a shallow copy of font, we must guarantee that the copied font
will not be deleted until the shallow copy is deleted. So need to
increase the src font's refcount when copying it;
--The stream |m_pOwnedStream| needs to have matched new/delete
These errors need to be fixed before we can properly delete all the
fonts to address the leaks.

Two leak cases are addressed here:
--In CFGAS_FontMgrImp::LoadFont(), calling LoadFace() is unnecessary
since the following LoadFile() does the exact same thing. Calling
LoadFace() without releasing the loaded face results in a leak;
--|m_Hash2Fonts| in class CFGAS_FontMgrImp owns all the fonts stored
in it. The fonts need to be deleted along with the container.

The GEFont points to the font manager which creates it and tries to unregister
itself. Currently the GEFont can be created by the default mapper and then
stored in a different mapper. If the default mapper is destroyed first, when
the second mapper cleans up the font there will be a call to unregister on
the default mapper causing a use-after-free.
The long term fix is to fixup the GEFont so it points to the correct mapper
to unregister from. This CL forces the destruction order in CXFA_FFApp to
cleanup the non-default mapper first.

This change mainly contains files in xfa/ and fxjse/ directories
which were not covered by previous changes.
This is part of the efforts to make PDFium code compilable
by Clang chromium style plugins. After this change, PDFium can be
compiled with "clang_use_chrome_plugin=true" for GN build. Since
clang_use_chrome_plugin is true by default, we no longer need to
set this parameter explicitly.
The changes are mainly the following:
-- move inline constructor/destructor of complex class/struct out-of-line;
-- add constructor/destructor of complex class/struct if not
explicitly defined;
-- add explicit out-of-line copy constructor when needed;
-- move inline virtual functions out-of-line;
-- Properly mark virtual functions with 'override';
-- some minor cleanups;
