[code-reflection] RFR: Catching and logging exceptions from BodyScanner::scanLambda when reflectAll enabled

[Adam Sotona]

[PR: Implementation of -XDreflectAll switch](https://github.com/openjdk/babylon/pull/822) wrapped `BodyScanner::scanMethod` with try/catch block and logged warnings when `reflectAll` enabled.
This PR also wraps `BodyScanner::scanLambda` to enable `reflectAll` testing.

Please review.

Thank you,
Adam
