resolves #13141

This PR adds a new method to the cloudflare SDK, instrumentD1WithSentry. This method can be used to instrument Cloudflare D1, Cloudflare's serverless SQL database.

// env.DB is the D1 DB binding configured in your `wrangler.toml`
const db = instrumentD1WithSentry(env.DB);
// Now you can use the database as usual
await db.prepare('SELECT * FROM table WHERE id = ?').bind(1).run();

The reason this has to be a standalone wrapper method instead of an integration is because the cloudflare d1 instance can be bound to any arbitrary environmental variable as per user config. This is why the snippet above shows env.DB being passed into instrumentD1WithSentry. env.DB can easily be env.COOL_DB or env.HAPPY_DB.

I am planning to ask the cloudflare team to expose some APIs to make this better, but in the meantime this is the best we can do.
