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.
