[code-reflection] RFR: Add isQuotable attribute to LambdaOp [v7]

[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.

Mourad Abbay has updated the pull request with a new target base due to a merge or a rebase. The incremental webrev excludes the unrelated changes brought in by the merge/rebase. The pull request contains eight additional commits since the last revision:

 - Merge branch 'code-reflection' into lambda-isQuotable-attr
 - Apply suggestion
 - Rectify the way we get the flags of a lambda invokedynamic
 - Correct the way we detect if a lambda is quotable when lifting bytecode
 - Update expected models in tests to include the attribute
 - Detect if a lambda is quotable when lifting bytecode
 - Apply review comments
 - Add attribute to LambdaOp
