[Bug]: missing input flag on input model

[jhendrixMSFT]

Describe the bug

Input and Output UsageFlags need to be transitively set. i.e. if type Foo has flag Input set, then all of its transitive types must also have Input set.

Reproduction

Build https://github.com/Azure/azure-rest-api-specs/tree/main/specification/quantum/Quantum.Workspace

Type JobDetails has UsageFlags.Input set. It contains a field of type CostEstimate that does not have the Input flag set.
