Add support for creating non-meta tags with v2_meta

[chaance]

This PR adds support for generating <script type='application/ld+json' /> and meta-related <link /> tags to document head via the route meta function when using the v2_meta future flag. This is useful for things like canonical URLs, alternate language references and structured data JSON.

The added API looks like this:

export function meta({ data }) {
  let { author } = data;
  return [
    { title: data.name + " Profile" },
    {
      // <link rel='canonical' href='https://website.com/authors/1'>
      tagName: "link",
      rel: "canonical",
      href: "https://website.com/authors/" + author.id,
    },
    {
      // <script type='application/ld+json'>{ ... }</script>
      "script:ld+json": {
        "@context": "http://schema.org",
        "@type": "Person",
        name: author.name,
        address: {
          "@type": "PostalAddress",
          streetAddress: author.address.streetAddress,
          addressLocality: author.address.city,
          addressRegion: author.address.state,
          postalCode: author.address.zip,
        },
        email: author.emails,
      },
    },
  ];
}

While both technically work (React renders nested arrays of arrays just fine), the output of map doesn't match our return type API.
