[Chromoting] Enable remoting webapp main.html GN build.

This is a re-land of crrev.com/1082083005

The previous remoting webapp GN build files were not enabled and at
least 6 months out of date. This cl fixes the problem by bringing
the build rules up to date and enables the webapp build.

It also starts to move all the remoting-specific build rules into
the remoting dir rather than having them in the main build.gn file.
