Console logs occasionally skipped before shutdown

[JacksonKearl]

const delay = () => new Promise(resolve => setTimeout(resolve, 14));

(async () => {
  console.log('1')
  await delay()
  console.log('2')
  await delay()
  console.log('3')
  await delay()
  console.log('4')
  await delay()
  console.log('5')
  await delay()
  console.log('6')
  await delay()
  console.log('7')
  await delay()
  console.log('8')
  await delay()
})()

Try running this a few times, if you see no output increase delay if you see full output decrese it. At around 11-14ms I see anywhere between no output and full output, with the output sometimes reordered.

We need a change in the DAP to solve this properly: microsoft/debug-adapter-protocol#85

Update on this since there have been a few duplicates: we now use the behavior of the previous debug adapter where we stringify simple messages directly, so those should not be missed. However, if a message includes complex data that we need to send as variables, we can still hit the scenario I described in the linked issue.

Some improvements made here 02f9147 but the scenario with variable references is still present
