MethodHandle composability fix

Standardize the processing path for MethodHandles invoked in
transforms with EmulatedStackFrame arguments. The EmulatedStackFrame
contains the actual arguments to perform the invoke with. Previously,
we did not compose well with wrapped targets, such as MethodHandles
wrapping VarHandle instances.
