CmdPal: Add CmdPalLogger, Provider, and extension method

[michaeljolley]

This pull request introduces a new logging infrastructure for the CmdPal module by integrating the Microsoft.Extensions.Logging (MEL) abstraction and routing all log output through the existing ManagedCommon.Logger. The changes add a custom logger, logger provider, and extension method for easy registration, and update dependencies and service configuration to enable the new logging system.

This logging is not in use currently, but will be in a future PR.

Logging Infrastructure Integration:

• Added a new CmdPalLogger class implementing ILogger, which delegates logging calls to ManagedCommon.Logger to centralize and standardize log output.
• Implemented CmdPalLoggerProvider to create and manage CmdPalLogger instances, allowing MEL-based logging throughout the application.
• Introduced CmdPalLoggingExtensions.AddCmdPalLogging for registering the logger provider via dependency injection, ensuring all MEL logging is routed appropriately.
• Updated App.xaml.cs to register the new logging system with services.AddCmdPalLogging(), enabling the infrastructure at application startup. [1] [2]

Project and Dependency Updates:

• Updated the project file Microsoft.CmdPal.Common.csproj to reference the ManagedCommon project and to include a folder for the new logging code. [1] [2]
