This fixes two partially interrelated bugs with font loading in XFA
documents. First, it adds falling back to the builtin fonts if there
are no viable embedded or installed font for the top-level XFA font
manager. Additionally it changes the load font code path in
CXFA_FWLTheme to use the top level XFA font manager, instead of the
one that just handles the system installed fonts.
The main visible issue that this patch fixes is that currently using
--font-dir with pdfium_test on a XFA PDF can cause text to not be
displayed in widgets and/or NOTREACHED asserts. This occurs if there
isn't a needed fonts embedded in the document or in the font
directory, since currently PDFium will not correctly fall back to the
builtins.

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.

Automated using git grep & sed.
Replace StringC classes with StringView classes.
Remove the CFX_ prefix and put string classes in fxcrt namespace.
Change AsStringC() to AsStringView().
Rename tests from TEST(fxcrt, *String*Foo) to TEST(*String*,
Foo).
Couple of tests needed to have their names regularlized.

There currently exists a weird split where some files exist in xfa/fxfa
and some files exist in xfa/fxfa/app. This CL removes the app/ folder
and moves all files up to the parent directory.
