dispatch namespace features

[aaronlisman]

Description

Adds support for several Workers for Platforms features:

• dispatch namespace bindings
• uploading workers 'to' a dispatch namespace

Also includes a few internal-ish items:

• 'unsafe' bindings, similar to wrangler's: feat: support for raw "unsafe bindings" workers-sdk#411
• 'pipeline_hash', which is used internally and in a few experimental features. This is also present in wrangler: https://github.com/cloudflare/workers-sdk/blob/1ce32968b990fef59953b8cd61172b98fb2386e5/packages/wrangler/src/deploy/deploy.ts#L635

Has your change been tested?

Yes, besides pipeline_hash, but they've only been tested against the mock handlers in the included tests.
