Move xfa/fwl/core to xfa/fwl.
The core/ directory in FWL no-longer provides any context. This Cl moves all of the core/ files up to the fwl/ folder. As well, the CFWL_EvtFoo files are renamed CFWL_EventFoo and the CFWL_MsgFoo files are renamed CFWL_MessageFoo. The event and message preceed the type in order to keep the files sorted together and to make it clear that they're all related. Review-Url: https://codereview.chromium.org/2559173002
