    Original change's description:
    > [wasm] Split compilation in three stages
    >
    > In order to refactor ownership between objects in wasm compilation, the
    > compilation (executed by background tasks) is split in three stages:
    > getting a compilation unit (while holding a mutex), executing the work
    > (without any mutex and without keeping the NativeModule alive), and
    > submitting the work (with a mutex again).
    >
    > This CL prepares this design by splitting compilation from submission.
    > Both steps are still executed right after each other. This will be
    > changed in a follow-up CL.
