app: add shiny backend

Combined with the outstanding shiny CLs and prebuilt ANGLE dlls in the
right place, this makes it possible to run example/basic on a windows
machine.

Eventually this shiny backend will also replace the app package's
custom darwin_amd64 and linux_x11 backends.

For golang/go#9306
