[MLIR][Python] Add a python function to apply patterns with MlirOperation (#157487)
In https://github.com/llvm/llvm-project/pull/94714, we add a python
function `apply_patterns_and_fold_greedily` which accepts an
`MlirModule` as the argument type. However, sometimes we want to apply
patterns with an `MlirOperation` argument, and there is currently no
python API to convert an `MlirOperation` to `MlirModule`.
So here we overload this function `apply_patterns_and_fold_greedily` to
do this (also a corresponding new C API
`mlirApplyPatternsAndFoldGreedilyWithOp`)
