[code-reflection] RFR: Add isQuotable attribute to LambdaOp

[Mourad Abbay]

In the `interpreter` and `ByteCodeGenerator` we detect if a lambda is quotable based on its functional interface. This approach will not work if intersection type is used e.g. `Runnable r = (Runnable & Quotable) () -> {};` This PR adds a flag to LambdaOp that will be set by the `javac` for quotable lambdas.
