  [MLIR] Rerun control for actions in execution context (#209197)

Adds a Rerun control value to ExecutionContext::Control that allows the
re-execution of the current action immediately after it completes,
without restarting the full compilation pipeline. This is analogous to
GDB's ability to restart execution from a breakpoint. When the callback
returns Rerun, the action is executed normally, then re-dispatched
through the full ExecutionContext::operator() pipeline, including
breakpoint matching, so the user gets a fresh opportunity to inspect or
control the re-execution. As a practical usage example, a breakpoint +
an observer can be added, to save and restore IR between runs to check
if each run produces the same IR or something different each time. A
depth-keyed structure is used, so rerun requests survive nested action
dispatch and are consumed by the correct stack frame.
