Fix tuple resource list handling in mgmt generator

[ArcturusZhang]

Summary

• classify basic array-returning operations as resource list methods
• support tuple-resource intermediate collection paths by matching operation paths as prefixes of resource instance paths
• emit all collection GetAll overloads when multiple list operations target the same resource collection

Validation

• npm exec -- vitest run -c .\emitter\vitest.config.ts .\emitter\test\resource-detection.test.ts
• npm run prettier
• npm run lint
• dotnet test eng\packages\http-client-csharp-mgmt\generator\Azure.Generator.Management\test\Azure.Generator.Mgmt.Tests.csproj --filter ResourceCollectionClientProviderTests
• RegenSdkLocal.ps1 -Services "Azure.ResourceManager.Compute" -LocalSpecRepoPath "C:\Users\dapzhang\Documents\workspace\spec-compute-wt"
