Alexander Aprelev 4138277ee6 [vm/shared] Introduce 'vm:shared' pragma.

Decorating a field with 'vm:shared' pragma makes values in this field accessible to all isolates in an isolate group.

Introduce `channel` to the `Version` class so that the pragma can only be enabled on main and dev channels.

Shared memory

https://github.com/dart-lang/language/blob/main/working/333%20-%20shared%20memory%20multithreading/proposal.md provided a framework for adding shared memory support to applications running on dart vm.

First, support for pragma("vm:shared") was added, which could be put on static fields. Static fields decorated with such pragma become shared by all isolates in isolate group.
