Matthias Howell 8e1998ddcb .NET: Adds Valkey to chat message history - issue 5445 (#5542) ...

* Adds Valkey to chat message history

* Address review: switch to Valkey.Glide, add options class, remove context provider

- Switch from StackExchange.Redis to Valkey.Glide 1.1.0 (official Valkey .NET client)
- Extract optional params into ValkeyChatHistoryProviderOptions
- Add JsonSerializerOptions support, remove [RequiresUnreferencedCode]
- Make MaxMessages/MaxMessagesToRetrieve readonly via options
- Remove ValkeyContextProvider (overlaps with ChatHistoryMemoryProvider + MEVD)
- Remove ValkeyProviderScope (only used by context provider)
- Remove connection string constructors (caller manages IConnectionMultiplexer)
- Update samples to use new API and gpt-5.4-mini

* Use type-safe JsonSerializer overloads, remove suppress attributes

Use JsonSerializerOptions.GetTypeInfo() for Serialize/Deserialize calls
to enable NativeAOT/trimming compatibility without suppress attributes.
Default to AgentAbstractionsJsonUtilities.DefaultOptions when no options provided.

* Update READMEs: remove context provider references

Remove ValkeyContextProvider and long-term memory references from sample
READMEs since the context provider was removed from this PR. Simplify
Valkey server requirements (no search module needed for chat history).
