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).
