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) R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1776303002 .
