feat(wrangler): add local DO support with getPlatformProxy

[edmundhung]

Fixes n/a.

The getPlatformProxy() API was designed for framework integrations on Cloudflare Pages with DO support limited to external workers only (i.e. DO with script_name specified).

This PR enables local DO binding support (including RPC) if the user is building on Cloudflare Workers (e.g. with Static Assets).

Really looking forward to this support!

Currently this is what I have for my setup and tests 🙂

1. wrangler.toml (prod)
2. wrangler-local.toml (with script_name = "do-worker" pointing to external DO worker)
3. wrangler-do.toml (without script_name to run DO locally)
4. wrangler-test.toml (for tests - to run tests without DO)
