Add support for method reference suggested based on type parameters

[gayanper]

	private Map<Class<? extends KtElement>, Function<KtElement, IHyperlink[]>> factories;

	private void initFactories() {
		this.factories.put(KtNameReferenceExpression.class, **HERE**)
	}

	private IHyperlink[] createForNameReferenceExpr(KtElement element) {
		return null;
	}

should suggest this::createForNameReferenceExpr
