feat(client-telemetry-utils): Retain inner error as cause when wrapping errors

[jason-ha]

but do not log cause property itself.

[Copilot]

Pull Request Overview

This PR adds support for preserving inner errors as the cause property when wrapping errors, following the ES2022 Error.cause standard. The key change ensures that when errors are wrapped, the original error is retained for debugging purposes while preventing the cause property itself from being logged as telemetry data.

Key changes:

• Added cause property to IFluidErrorBase interface with comprehensive documentation
• Modified wrapError function to set the cause property to the inner error
• Updated LoggingError class to exclude the cause property from telemetry logging
• Added comprehensive test coverage for the new functionality
