debuginfo: Fix bug in type name generation for dyn types with associated types but no other generic arguments. For types like `&dyn Future<Output=bool>` the compiler currently emits invalid types names in debuginfo. This PR fixes this. Before: ```txt // DWARF &dyn core::future::future::Future, Output=bool> // CodeView ref$<dyn$<core::future::future::Future,assoc$<Output,bool> > > > ``` After: ```txt // DWARF &dyn core::future::future::Future<Output=bool> // CodeView ref$<dyn$<core::future::future::Future<assoc$<Output,bool> > > > ``` These syntactically incorrect type names can cause downstream tools (e.g. debugger extensions) crash when trying to parse them. r? `@wesleywiser`
