Revert "[vm] Replaces fuchsia.deprecatedtimezone"

This reverts commit 9474c23.

Reason for revert: Doesn't compile (?)

Original change's description:
> [vm] Replaces fuchsia.deprecatedtimezone
>
> (prior attempt was rolled back as it had a regression which was not
> caught by tests.  Tests are fixed now at:
> https://fuchsia-review.googlesource.com/c/fuchsia/+/409840)
>
> The FIDL library fuchsia.deprecatedtimezone is going away.  There are
> different and better ways to obtain the same functionality.  This change
> removes the dependency on fuchsia.deprecatedtimezone from the Dart SDK.
>
> Adds inspect metrics that allow whitebox testing of the runners.  Here's
> a sample `fx iquery` excerpt from a running device, showing both a dart
> and a flutter runner exposing the same OS diagnostic metrics.
>
> Adds support for asynchronous timezone updates, which was missing from
> previous versions of this commit.
