Feature request: Add support for AppSync GraphQL batch resolvers

[dreamorosi]

Use case

In #3999 we added support for AppSync GraphQL single resolver, which allows customers to map a GraphQL action/request to a resolver. We should now add batch resolvers.

Solution/User Experience

Building on the APIs introduced in #3999, we should add a new method batchResolver that accepts a resolver function and a configuration/options object. The config object should work similar to the resolver method added in the PR mentioned above and accept typeName and fieldName. The main difference for this new method is that it passes a list of AppSyncResolverEvent to the route handler.
