Limitation for tsp to handle operation id from swagger

[tadelesh]

For tsp, interface name could not be same with the model name, meanwhile, interface name will be recognized as operation id for SDK and generated swagger. However, for some RP, model name is same with the operation id, see example.

Two possible solutions:

1. use @projectedName to rename interface, but current typespec-autorest does not honor @projectedName.
2. introduce another new decorator in typespec-azure-resource-manager to identify operation id for each operation.

I prefer 2.

@tadelesh The correct thing to do here is to use the client name projection to set the operationId

Here is a sample showing the OperationId changing when the client projected name of the interface is changed

Thanks @markcowl . Implemented in converter: Azure/autorest@054fdf8
