Reland "Improve handling of disable-dartdev-analytics"

Browse source 
This is a reland of 58860f4814

Original change's description:
> Improve handling of disable-dartdev-analytics
>
> This is second try of https://dart-review.googlesource.com/c/sdk/+/171284
> that was reverted to to faulty logic in main_options.
>
> Some other refactorings are piggy-backed along.
>
> TestProject.runSync no longer takes a 'command' argument. It was anyway
> often not an argument.
>
> Also stop the messy handling of pub arguments. It is no longer needed.
>
> BUG: https://github.com/dart-lang/sdk/issues/44135
> Change-Id: I49abf5810d9ea262409ba9d93f0471037cb8a753
> TEST=The VM change is tested via all the pkg/dartdev/test/command/* tests that invoke dart with the --no-analytics flag.
> TEST=Furthermore manual test that the --no-analytics flag is passed to dartdev.
> Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/174261
