Make mojo/services pass in "gn check"

Make mojo/services pass in "gn check"

This mostly just adds the missing dependency identified by the checker.

In some cases I looked at the target and added public_deps that I thought were appropriate given the nature of the target.

This renames the generated mojo action names to be foo__generator instead of foo_generator since it is not clear from the current name that it is an internally-generated target and I kept trying to use it. The double-underscore matches the Android generated targets.

In a few cases I changed ordering (sources come before deps in GN style) but I didn't want to make the changes difficult to diff so didn't do it for most cases.
