Add unit tests and logging infrastructure for InMemory and RabbitMQ transports

- Implemented RecordingLogger and RecordingLoggerFactory for capturing log entries in tests.
- Added unit tests for InMemoryChannel, covering constructor behavior, property assignments, channel communication, and disposal.
- Created InMemoryTransportOptionsTests to validate default values and customizable options for InMemory transport.
- Developed RabbitMqFrameProtocolTests to ensure correct parsing and property creation for RabbitMQ frames.
- Added RabbitMqTransportOptionsTests to verify default settings and customization options for RabbitMQ transport.
- Updated project files for testing libraries and dependencies.
