Move samples into services and remove language resolver

[praveenkuttappan]

Samples restructure to follow the pattern used by language service.

[Copilot]

Pull Request Overview

This PR restructures the sample generation architecture to consolidate sample-related code within the language services directory and eliminates the language-specific resolver pattern. The changes simplify the dependency injection model by making SampleLanguageContext a property directly accessible from each LanguageService instead of requiring resolution through a separate service.

• Moved all sample generation classes from Azure.Sdk.Tools.Cli.Samples to Azure.Sdk.Tools.Cli.Services.Languages.Samples.SampleGeneration namespace
• Removed the ILanguageSpecificResolver<T> and its implementation, eliminating dynamic language detection logic
• Added SampleLanguageContext as a property on LanguageService base class, instantiated via a switch expression
• Updated all LanguageService implementations to accept IFileHelper in their constructors
