Following #13134, this PR now exports a second function, getTraceMetaTags that gives users an easy way to get stringified Html meta tags for server->client trace propagation.

Example usage:

app.get('/', (_req, res) => {
  res.send({
    response: `
    <html>
      <head>
        ${Sentry.getTraceMetaTags()}
      </head>
      <body>
        Hi :)
      </body>
    </html>
    `,
  });
});

API design note:

We briefly discussed returning an array of strings per meta tag instead of just one string. If reviewers prefer this, I'm happy to change the API accordingly but my thinking was that users should always add all meta tags returned by this function. Otherwise, the propagated trace state would be inconsistent. So I don't want to hand them an API that suggest they could pick one. Also, returning an array would make the API a tad less convenient to use and there's precedence for the simple string approach, for example in Laravel.
