204d301bb1 [mlir][Python] Fix lifetime of ExecutionEngine runtime functions. 
We weren't retaining the ctypes closures that the ExecutionEngine was
calling back into, leading to mysterious errors.

Open to feedback about how to test this. And an extra pair of eyes to
make sure I caught all the places that need to be aware of this.

f05ff4f757 [mlir][python] Apply py::module_local() to all classes. 
* This allows multiple MLIR-API embedding downstreams to co-exist in the same process.
* I believe this is the last thing needed to enable isolated embedding.

0cdf491501 Break apart the MLIR ExecutionEngine from core python module. 
* For python projects that don't need JIT/ExecutionEngine, cuts the number of files to compile roughly in half (with similar reduction in end binary size).
