[jdk17] RFR: JDK-8269426: Rename test/jdk/java/lang/invoke/t8150782 to accessClassAndFindClass [v2]

[Mandy Chung]

> `test/jdk/java/lang/invoke/t8150782` is the only one using that convention. There are several tests under `<bugid>` directory.  As the tests under `test/jdk/java/lang/invoke/t8150782` are mostly unit tests for `Lookup::accessClass` and `Lookup::findClass`, they can simply be moved to the parent directory.

Mandy Chung has updated the pull request incrementally with one additional commit since the last revision:

  Keep the tests under a directory
