Stella Laurenzo	543922cd36	Adds MLIR C-API for marshaling Python capsules. * Providing stable, C-accessible definitions for bridging MLIR Python<->C APIs, we eliminate inter-extension dependencies (i.e. they can all share a diamond dependency on the MLIR C-API). * Just provides accessors for context and module right now. * Needed in NPComp in ~a week or so for high level Torch APIs.

Stella Laurenzo	85185b61b6	First pass on MLIR python context lifetime management. * Per thread https://llvm.discourse.group/t/revisiting-ownership-and-lifetime-in-the-python-bindings/1769 * Reworks contexts so it is always possible to get back to a py::object that holds the reference count for an arbitrary MlirContext. * Retrofits some of the base classes to automatically take a reference to the context, elimintating keep_alives. * More needs to be done, as discussed, when moving on to the operations/blocks/regions.

First pass on MLIR python context lifetime management.

* Per thread https://llvm.discourse.group/t/revisiting-ownership-and-lifetime-in-the-python-bindings/1769
* Reworks contexts so it is always possible to get back to a py::object that holds the reference count for an arbitrary MlirContext.
* Retrofits some of the base classes to automatically take a reference to the context, elimintating keep_alives.
* More needs to be done, as discussed, when moving on to the operations/blocks/regions.
