feat(nuxt): Add Cloudflare Nitro plugin

[s1gr1d]

⚠️ This PR is a work-in-progress and APIs and naming might change

A plugin which initializes Sentry when deployed to Cloudflare.

1. Remove the previous server config file: sentry.server.config.ts
2. Add a plugin in server/plugins (e.g. server/plugins/sentry-cloudflare-setup.ts)
3. Add this code in your plugin file

   // server/plugins/sentry-cloudflare-setup.ts (filename does not matter)
   import { cloudflareNitroPlugin } from '@sentry/nuxt/module/plugins'
   
   export default defineNitroPlugin(cloudflareNitroPlugin({
       dsn: 'https://dsn',
       tracesSampleRate: 1.0,
   }))

Addition to the Cursor comments:

• Although the type is different (H3Event and CfEventType), both share the same context.cf property.
• The meta tags are always strings. It's based on the type definition of Nuxt.
