Philip Chimento 24def913ec Remove support for nested Temporal time zone property bags
Previously, "nested" time zone property bags were unwrapped up to one
level. That is, this object:
{
  timeZone: {
     // ...Temporal.TimeZone methods
  }
}
would not be considered to implement the TimeZone protocol, but would have
its timeZone property used instead, if it were passed to an API that
required a TimeZone protocol object.

These nested property bags are no longer supported. Discussion:
