support AWS::Type::AppSync::FunctionConfiguration in artifact_exporter

[xentek]

Adds support to artifact_exporter for the new CloudFormation type AWS::Type::AppSync::FunctionConfiguration (specifically the RequestMappingTemplateS3Location ResponseMappingTemplateS3Location properties).

There was already an existing PR (#3822) but it hasn't seen any activity for over 25 days. This PR improves upon the original by adding tests for not only the AppSyncFunctionConfigurationRequestTemplateResource and AppSyncFunctionConfigurationResponseTemplateResource classes, which were introduced in this pull but also tests for AppSyncResolverRequestTemplateResource and AppSyncResolverResponseTemplateResource that were introduced in a previous change.

fixes #3816

@sanathkr @justnance Just updated this PR with the latest from aws/aws-cli@develop. Any chance we can merge this soon so I don't have to continue to maintain and use my fork in my own workflow?

Thanks!
