JVM_IR: Fix Inline CallableReferences with Varargs

- Added tests to demonstrate broken behaviour: the interaction of inline
  functions and callable references with varargs and defaults in various
  combinations.
- Refactored InlineCallableReferencesToLambdaPhase to look like and use
  some of the infrastructure from CallableReferenceLowering.
- Lifted some of this infrastructure out to be broadly reusable.
