🗺 API updates for v2 meta arguments and types

[chaance]

This PR does a few things we'll want to include behind the v2_meta flag before the major release.

• V2_HtmlMetaDescriptor has been renamed to V2_MetaDescriptor. This is shorter but also more aligned with the links function return value type, which is LinkDescriptor. It also makes a bit more sense as we support values for other HTML tags than <meta>.
• V2_HtmlMetaDescriptor and V2_HtmlMetaFunction types should be imported from @remix-run/react instead of @remix-run/<runtime> since A) the primary responsibility of meta is rendering, and B) matches data only makes sense in the context of an app calling useMatches. I think we should follow suit here with LinksFunction in v2, but that's for a separate PR.
• The meta function's arguments have been simplified
  • parentsData has been removed, as each route's loader data is available on the data property of its respective match object

    // before
    export function meta({ parentsData }) {
      return {
        title: parentsData['routes/some-route'].title,
      };
    };
    // after
    export function meta({ matches }) {
      return {
        title: matches.find((match) => match.id === 'routes/some-route').data.title,
      };
    };

  • The route property on route matches has been removed, as relevant match data is attached directly to the match object

    // before
    export function meta({ parentsData }) {
      let rootModule = matches.find(match => match.route.id === "root");
    };
    // after
    export function meta({ matches }) {
      let rootModule = matches.find(match => match.id === "root");
    };
