feat: update CloudFormation resources v2.18.0 (#1407)

New resource types:

* AWS::AmazonMQ::ConfigurationAssociation
* AWS::IoTAnalytics::Channel
* AWS::IoTAnalytics::Dataset
* AWS::IoTAnalytics::Datastore
* AWS::IoTAnalytics::Pipeline

Misc:

* Patch ServiceDiscovery resource "Map" primitive type to "Json" (see #1409)
* Relax namespaces test so we don't have to update it every time we update the spec
* Rewrite the create-missing-libraries script in typescript so it's a bit more robust and mangles names nicely.
