Merge #11935

11935: [go/sdk] Delegate alias computation to the engine r=Zaid-Ajaj a=Zaid-Ajaj


# Description

This PR removes the use of `collapseAliases` from the go SDK which used to calculate aliases of resources from `ResourceOptions` and their inherited child aliases (a.k.a. alias explosion) and starts using the new alias specification `pulumirpc.Alias` that is handled by the engine in a language-agnostic manner. 

This PR removes `aliases: []URNOutput` from `resourceState` because we no longer have to keep track of them in `makeResourceState` but instead calculate them in `prepareResourceInputs`. 

Fixes #11066
Potentially addresses #11697
