Singleton enums are not typed properly

[rix0rrr]

An enum with a single value is type-inferred by TSC to be some thing that we have no support for.

I looked into it for a bit, it's not trivial to extend it though.

@rix0rrr do you have a concrete case where a single-entry enum is used?

I had one but I removed it (because obviously we can do without)

An example in @aws-cdk/aws-ec2 is the type of VPN connection. Currently, the only valid value is ipsec.1.

See the discussion with @eladb here aws/aws-cdk#1899 (comment).
