Issue details

In some cases (like #1819), CloudFormation incorrectly labels a resource as supported (visibility = PUBLIC, provisioning-type = FULLY_MUTABLE) even though they are not.
In such cases we essentially include a broken resource in the provider.

We should add the ability to mark certain resources as not supported and overwrite CloudFormations results with that here:

pulumi-aws-native/provider/cmd/pulumi-gen-aws-native/main.go

Lines 246 to 250 in 5a71999

	out, err := cfn.ListTypes(ctx.Background(), &cloudformation.ListTypesInput{
	Visibility: "PUBLIC",
	ProvisioningType: provisioningType,
	NextToken: nextToken,
	})
