Support AWS::CloudFormation::ResourceTypeConfig

### Name of the resource

### Resource name

AWS::CloudFormation::ResourceTypeConfig

### Description

Custom resource types published to the registry support ["account-level" configuration](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/registry-private.html#registry-set-configuration).

Hooks are similar and have an `AWS::CloudFormation::HookTypeConfig` resource type that allows setting configuration for the hook.

Unfortunately, resource types don't have the same support, so customers need to implement a custom resource to configure their custom resource type if they want to deploy their custom resource type using CloudFormation.

It would be _fantastic_ if we had an `AWS::CloudFormation::ResourceTypeConfig` that allowed us to set the "account-level" configuration for a resource provider more easily.

### Other Details

It seems like this would be relatively straightforward to implement by cloning the [existing resource implementation](https://github.com/aws-cloudformation/aws-cloudformation-resource-providers-cloudformation/tree/master/aws-cloudformation-hooktypeconfig) and updating it to make the appropriate API call to update the resource type configuration instead of the hook configuration.

Start in the existing aws-cloudformation-hooktypeconfig resource implementation linked in the issue, then compare its hook configuration API call with the CloudFormation API for resource type configuration. Done means a corresponding AWS::CloudFormation::ResourceTypeConfig resource can set account-level configuration for a published custom resource type.
