[Generation] Untyped node support

[andrueastman]

This PR

• Fixes Provide a way to deserialize properties that could be of "any" type. #2548
• Fixes How can we handle untyped JSON? #2319

It adds generation support for deserialization of properties that have an unknown type("any") in the generation of C#, Go, Typescript and Java by introduction of the generation of the UntypedNode type in such scenarios.

In summary changes include

• Generation of the UntypedNode type in Go,C#,Java and TS while calling RemoveUntypedNodePropertyValues to prevent generation in other langs.
• Adds "apisguru::apis.guru" api to integration test to validate the same and should pass once abstractions libs are released.

End to end tests performed with the "apisguru::apis.guru" api can be validated/tested with the samples here that pull these changes as submodules.

Excellent work! We'll need to update the changelog once libraries are published but nothing to add besides that.
