.Net: [Feature Branch] Vector Store Logging - #10865

Motivation and Context

Related: #10596

This PR enhances the vector store functionality by adding builder pattern implementations and logging decorators for key vector data interfaces, along with supporting utilities and DI integration.

Interfaces handled:

• IKeywordHybridSearch<TRecord>
• IVectorizableTextSearch<TRecord>
• IVectorizedSearch<TRecord>
• IVectorStore
• IVectorStoreRecordCollection<TKey, TRecord>

Class types added:

• Builders: implement a pipeline pattern with Use and Build methods.
• Logging Extensions: provide reusable logging methods for tasks and enumerables, handling success, failure and cancellation.
• Logging Decorators: wrap the interfaces to add logging by using LoggingExtensions reusable logging methods.
• Builder Extensions: Add AsBuilder methods to convert service instances into builders.
• Logging Builder Extensions: Add UseLogging methods to integrate logging into builder pipelines.
• Service Collection Extensions: Add Add{T} and AddKeyed{T} methods for DI registration with configurable lifetimes.

Other changes:

• Split Verify class into Verify and KernelVerify in order to be able to use Verify methods in Microsoft.Extensions.VectorData package without a reference to Semantic Kernel specific logic, like ValidPluginName, ValidFunctionName etc.
• Added unit tests for new classes and methods.
• Added usage example in Concepts/Memory folder.

Usage example

Logging with manual registration:

var vectorStore = new InMemoryVectorStore()
    .AsBuilder()
    .UseLogging(this.LoggerFactory)
    .Build();

Logging with DI:

serviceCollection.AddInMemoryVectorStore();

serviceCollection
    .AddVectorStore(s => s.GetRequiredService<InMemoryVectorStore>())
    .UseLogging(this.LoggerFactory);
