lambda: Add support for invoke-interface for boxed innate lambdas
Lambda closures created with the 'create-lambda' instruction
(termed "innate lambdas") can be turned into an object with 'box-lambda'.
This CL enables support for those kinds of lambdas to work with
'invoke-interface' by generating a proxy class for the lambda.
Note: MIPS32/64 support not included.
