feat(cloudflare): add service bindings

[F0rce]

Changes

• This change introduces Service bindings to the @astrojs/cloudflare adapter.
• Both setting the service bindings via astro.config.ts (pages type) and reading them from wrangler.toml (workers type) have been implemented.

Testing

Changes have been tested by updating the dev-runtime-pages and dev-runtime-workers fixtures and adding an integration test to z-dev-runtime-pages.test.js and dev-runtime-workers.test.js respectively.

Docs

Since this is a feature, it does not affect current users, but the documentation will need to be updated.
