- `FirTypeResolverImpl.resolveSymbol` cannot simply assert that a type
parameter only has a single qualifier, because code may be fed to the
compiler where a type parameter is the start of a type chain (see for
example the added `typeParameterChainInReturnType` test).
- The fix assumes that any multi-qualifier type parameter trivially
resolves to `null`, because such a chained type cannot exist.
