This CL replaces IFGAS_Stream with the only implementation CFGAS_Stream.
The CreateReadStream and CreateWriteStream methods are removed in favour
of calling MakeRetain directly.

This Cl moves CXFA_WideTextRead to be in the anonymous namespace of
IFGAS_Stream and adds a IFGAS_Stream::CreateWideStringReadStream()
method.
This is done so we have all the implementations of IFGAS_Stream
centralized.

This Cl renames the the fgas_stream files to match the internal
ifgas_stream class. The majority of the code in ifgas_stream.cpp is
moved into the anonymouse namespace.

Currently we use the size provided by clusterfuzz when initializing the
css syntax parser. This maybe incorrect as the CFX_WideString may have a
different count after converting to UTF. Use the wide string length instead
of the provided size.
We need to guard against strings that convert to blank when doing the wide
conversion so add an early exit.

This CL splits the files in xfa/fde/css into class per file and renames any
needed files to match the class names.
Update some of the classes to use std::stack.

This Cl removes the stream initializer from the FDE CSS parser. The only
consumer was the css fuzzer. The fuzzer has been moved to use the string
initializer to match the rest of the code.

This CL updates the possible FDE CSS enums to enum classes and fixes up any
instances of incorrect values being used. A few other cleanups and changes
were needed to complete the conversion.

IFGAS_Streams are not part of the IFX_Stream hierarchy, but
can be made from such.

It's a separate hierarchy unrelated to the IFX_*Stream classes.
Also rename CFX_Stream to CFGAS_Stream, and so forth.

This Cl splits out the CXFA_WideTextRead class into it's own file. The helper
methods have been moved into xfa_utils.cpp and their pre-declarations into
xfa_utils.h.
