Feature: `dispatch-namespace` option in `wrangler deploy`

[benycodes]

trafficstars

What this PR solves / how to test: Ability to deploy workers to dispatch namespaces (Workers for Platforms product).

Usage: wrangler deploy --dispatch-namespace <namespace>

This is an improvement to PR #2746 because:

• Correct terminology of 'dispatch namespace' used instead of 'platform namespace'.
• Excludes tasks related to routes. custom domains. cron/schedules, and queue consumers when dispatch-namespace option used (these features aren't supported in Workers for Platforms)
• Allows for any name to be used for the script when dispatch-namespace option used, because Workers for Platforms doesn't check script names
