script: Add interrupt() and terminate()

Wire up the new frida-core Script.interrupt() and terminate() methods:

  - interrupt() aborts any JavaScript currently executing, leaving the
    script loaded and able to run again.
  - terminate() interrupts execution and unloads the script, so one
    stuck in a long-running or infinite operation can still be torn
    down.
