Research MLIR action tracing

[igaray]

MLIR includes an interesting feature to help debug it's use called action tracing.
Research it's use, whether it would be useful, and determine an action plan to include the functionality.

This is a pretty big research issue.
Initial steps would be to:

• see what the action API in C++ looks like, and whether it is enabled/exposed in MLIR's C API.
• if not, see how much work it would be to expose it
• Issue a PR to melior to include it in the Rust bindings
• try out a minimal example, document what is possible with actions, and propose changes to native with a plan
