Make exception serialization settings used by Remoting secure by default

[olegsych]

• Deprecate the ExceptionDeserializationTechnique property of the FabricTransportRemotingSettings and change its default value from Fallback to Default.
• Deprecate the ExceptionSerializationTechnique property of the FabricTransportListenerSettings and change its default value from BinaryFormatter to Default.

PR Overview

This PR updates exception serialization and deserialization settings to enhance security by deprecating the legacy BinaryFormatter/Fallback defaults. The changes remove hard-coded default values in production code, mark the deprecated properties with Obsolete attributes using DeprecationMessage.RemotingV1, and update unit tests to use the new defaults.

• Removed the old branching logic in exception serialization to avoid using BinaryFormatter by default.
• Annotated deprecated enums and properties and updated log messages.
• Adjusted unit tests to remove usage of the deprecated default settings.

• The change in log severity (using WriteInfo instead of WriteWarning) in this deserialization branch should be verified to ensure it accurately reflects the error condition.
