Fixed generic interface specialization crashes (#6601): (#6688)

* Fixed generic interface specialization crashes:

- Add an export decoration to specialized generic interfaces.

* Fixed generic interface specialization crashes:

- Add an export decoration to specialized generic interfaces.
- Use getTypeNameHint(...) instead of a manual mangler.

* In cloneInstDecorationsAndChildren: specialize all linkage decorations, not just the exports.

- If a linkage decoration is already present, it is not specialized and replaced by the specialized one.
- If a specialization uses the TypeNameHint, sanitize it to be used as an identifier.
- Use the identifier name sanitizer from slang-mangle.

* Added tests/generics/generic-interface-linkage.slang

- See #6601 and #6688
