[mlir] Add CMake flags to properly enable Jit event listeners.
By default, the listeners do nothing unless linked in.
This revision allows the "Perf" and "Intel" Jit event listeners to be used.
The "OProfile" event listener is not enabled at this time,
the associated library structure is not well-isolated.
