In the GN build, libchromiumcontent is no longer a distinct library, but merely a container for a set of scripts and patches. Maintaining those patches in a separate repository is tedious and error-prone, so merge them into the main repo. Once this is merged and GN is the default way to build Electron, the libchromiumcontent repository can be archived.
