RFR: 8299505: findVirtual on array classes incorrectly restricts the receiver type [v3]

[Chen Liang]

> The access hack for array class clone is only applied to `checkAccess` but missing before call to `restrictProtectedReceiver`, causing the array receiver type to be incorrectly replaced by the lookupClass type. This patch fixes that and adds a test to ensure an original lookup resolves `clone` for both array classes (public) and Object (inherited protected) correctly, and restores the old MethodHandlesGeneralTest from [JDK-8001105](https://bugs.openjdk.org/browse/JDK-8001105) which ensures correctness for publicLookup (which is already correct).

  Make test MH invocation slightly more readable
