LOG: [mlir][target] RAII wrap moduleToObject timer to ensure call `clear` function (#136142)

As title, we need to call `Timer::clear` to avoid extra log like this:
```
===-------------------------------------------------------------------------===
                           ...

  Total Execution Time: 0.0000 seconds (0.0000 wall clock)

   ---Wall Time---  --- Name ---

        -----       Total
```
