release: Update NEWS and bump version for 1.20.0 release//
Ah~ had a @Hermet 's point!
It seems that the 'EFL_BETA_API_SUPPORT' cannot have the '@since'.
Well, i like to keep the since tags anyway, since its telling the information when the API was added in beta stage.
Once the API is getting stable the since tags are getting bumped to the correct version.
