Jon Ross-Perkins 9b194a31c9 Support modifiers on namespace, in theory. (#3462)
In theory because none are allowed. This is to improve consistency in
handle_decl_name_scope's modifier handling, removing the namespace
special-case.

I noticed there's a crash bug on `impl <declaration>` which I'll address
separately.

This builds on #3461.
