[core] Add structured logging to experimental mutable object components (#52484)

## Why are these changes needed?

To improve log parsing and filtering capabilities by adding structured
context to log messages using `WithField()`.

This PR addresses the following files in #52468:
- src/ray/core_worker/experimental_mutable_object_manager.cc
- src/ray/core_worker/experimental_mutable_object_provider.cc (No need
to improve after checking)
