Cleanup the xfa/src/fgas directory.

This CL moves the code from xfa/src/fgas/src up one level. It then takes the
headers in xfa/src/fgas/include and moves them to their correct folder. The
src/ and include/ directories are then removed.

In some cases, when moving from include/ there was another header with the
same name. Those headers were either folded together, or the content of the
conflicting folder moved to an anonymous namespace in the cpp file as they were
not used anywhere else.

Files with duplicate names as core/src/crt were renamed to be fgas_ instead of
fx_. (e.g. fgas_system.h, fgas_memory.h, fgas_stream.h)
