[WIP] Route nonthreadsafe Tasks to taskhosts in mt mode

[JanProvaznik]

Fixes #12196

Context

before we implement the mechanism for detection how to route tasks via interfaces we can have this intermediate solution for tasks in our repo that we convert to thread safe

Changes Made

1. NodeProviderOutOfProcTaskHost manages pools of TaskHosts of given architecture instead of one per each
2. allowlist for thread safe tasks

Testing

TBD

        </Copy>

        <Message Text="Copied @(CopiedFilesList->Count()) files to $(OutputDir)" Importance="High" />
    </Target>
</Project>

-> in binlog we see that message (on allowlist) is inproc, and that copy is outofproc
but this needs unit tests coverage too
