This PR replaces `log` with `tracing` instrumentation on XCM-related modules to significantly improve debugging capabilities for XCM execution flows. Continues #8724 and partially addresses #6119 by providing structured logging throughout XCM components, making it easier to diagnose execution failures, fee calculation errors, and routing issues. ## Key Features - **Consistent targets**: All components use predictable `xcm::*` log targets - **Structured fields**: Uses `?variable` syntax for automatic Debug formatting - **Zero runtime impact**: No behavioural changes, only observability improvements
