[Feature request] ZodError with meta

[ElYaiko]

When throwing a ZodError it would be very useful to return with it's defined meta().
So when using it with treeifyError, would return like:

const tree = z.treeifyError(result.error);
 
// =>
{
  meta: { title: "This is the title" },
  errors: [ 'Unrecognized key: "extraKey"' ],
  properties: {
    username: { errors: [ 'Invalid input: expected string, received number' ] },
    favoriteNumbers: {
      meta: { title: "Favorite numbers", description: "The favorites numbers" },
      errors: [],
      items: [
        undefined,
        {
          meta: {},
          errors: [ 'Invalid input: expected number, received string' ]
        }
      ]
    }
  }
}
