972f65a8 - [clang][NFC] Add documentation for `CastExpr::path()`. (#85623)

[clang][NFC] Add documentation for `CastExpr::path()`. (#85623) This didn't have any documentation, so I had to do some experimenting in godbolt when I used this in https://github.com/llvm/llvm-project/pull/84138, and my reviewer later also had some [questions](https://github.com/llvm/llvm-project/pull/84138#discussion_r1524855434) about this, so I figured it would be worth adding documentation.
