- `Proxy/getOwnPropertyDescriptor/call-parameters.js`
  Fixes a call to `Object.getOwnPropertyDescriptor` without the prop
  param. Not actually a huge problem, as the test wasn't depending on
  it.

- `Proxy/getOwnPropertyDescriptor/result-type-is-not-object-nor-undefined`
  This test asserted that `function() {}` should throw with the
  following spec step, which is incorrect, as functions are typed as
  `Object` in the spec.
  """
  1. If Type(trapResultObj) is neither Object nor Undefined, throw a
    TypeError exception.

harness: make $262.agent.waitUntil check if a typed array can be shared before proceeding.

Migrating all tests to this API is necessary to prevent tests from hanging indefinitely when a SAB is sent to a worker but the code in the worker attempts to create a non-sharable TypedArray (something that is not Int32Array or BigInt64Array). When that scenario occurs, an exception is thrown and the agent worker can no longer communicate with any other threads that control the SAB. If the main thread happens to be spinning in the $262.agent.waitUntil() while loop, it will never meet its termination condition and the test will hang indefinitely.

Because we've defined $262.agent.broadcast(SAB) in https://github.com/tc39/test262/blob/master/INTERPRETING.md, there are host implementations that assume compatibility, which must be maintained.
