Kannan 005d1849c6 Implement new task queue kind to send worker commands (#9899) ...

## What

Add support for `TASK_QUEUE_KIND_WORKER_COMMANDS` in the matching
service. This is a new task queue kind for server-to-worker
communication (e.g. activity cancellations). It is represented by a new
`WorkerCommandsPartition` type in the `tqid` package — analogous to how
`StickyPartition` represents sticky queues.

Also adds a distinct `partition` metric tag for worker-commands queues
so their traffic can be distinguished from user-facing normal queues in
metrics.

Depends on [#9900](https://github.com/temporalio/temporal/pull/9900).

## Why

Worker_Commands queue kind has different properties compared to a normal
user defined queue. So we created a separate kind. This allows us to
distinguish task queue metrics based on whether they are internal or
user created queue.

## How did you test it?

Unit tests covering metric tag generation for normal, sticky, and
worker-commands partitions.
