This reverts commit 65e3c9d3b1.
Reason for revert: package:logging, package:stack_trace and package:usage need to be migrated first.
Original change's description:
> [vm, service, observatory] Bang Bang (My Type System Shot Me Down).
>
> Port the service tests and Observatory to Dart 3.
>
> Changes from the original landing:
>
> - The old tests are copied to observatory_2 / service_2 so the service can still be tested when running a legacy mode program
> - The test harness is taught about 'service_2'
> - Observatory's package is added to front end's opt-in list
> - Fixed some places in the bot configuration matrix so ensure 'service' runs on legacy bots and 'service_2' on weak-mode bots
>
> The ported tests themselves are not changed.
