feat: use proxy shared secret in vite plugin

[BlankParticle]

This was a bit of a rabbit hole, I started by figuring out why the Host header while using vite plugin was different. I saw that wrangler dev doesn't have this issue, and traced it to this code in wrangler is implementation

https://github.com/cloudflare/workers-sdk/blob/main/packages/miniflare/src/workers/core/entry.worker.ts#L110-L113

with some figuring out, I found that wrangler used a shared proxy secret which in turn allows entry.worker.ts to rewrite the Host header to the url. So I did the same in the vite plugin.

this required me to drill through the plugin context to bunch of places, I didn't just pass the secret because just having ctx would be useful for other things in future. And with that, the Entry Worker now trusts vite's handler and I get my correct Host header.

Here is a reproduction of the issue: https://github.com/BlankParticle/cf-vite-plugin-host-header-reproduction
