RFR: 8330467: NoClassDefFoundError when lambda is in a hidden class

[Adam Sotona]

Current implementation of `LambdaMetafactory` does not allow to use lambdas in hidden classes. Invocation throws `NoClassDefFoundError` instead.

This patch includes lambda implementation in a hidden class under the special handling of `useImplMethodHandle`.
The patch also fixes `j/l/i/defineHiddenClass/BasicTest::testLambda` to correctly cover this test case.

Please review.

Thanks,
Adam
