b208e5bcd0 [mlir] Add Python bindings for IntegerSet 
This follows up on the introduction of C API for the same object and is similar
to AffineExpr and AffineMap.

74628c4305 [mlir] Add Python bindings for AffineExpr 
This adds the Python bindings for AffineExpr and a couple of utility functions
to the C API. AffineExpr is a top-level context-owned object and is modeled
similarly to attributes and types. It is required, e.g., to build layout maps
of the built-in memref type.

abb4cd3e74 [mlir][Python] Initial Affine Map Python Bindings. 
- Add `PyAffineMap` to wrap around `MlirAffineMap`.
- Add `mlirPythonAffineMapToCapsule` and `mlirPythonCapsuleToAffineMap` to interoperate with python capsule.
- Add and test some simple bindings of `PyAffineMap`.

bd2083c2fa [mlir][Python] Python API cleanups and additions found during code audit. 
* Add capsule get/create for Attribute and Type, which already had capsule interop defined.
* Add capsule interop and get/create for Location.
* Add Location __eq__.
* Use get() and implicit cast to go from PyAttribute, PyType, PyLocation to MlirAttribute, MlirType, MlirLocation (bundled with this change because I didn't want to continue the pattern one more time).

ad958f648e [mlir][Python] Add missing capsule->module and Context.create_module. 
* Extends Context/Operation interning to cover Module as well.
* Implements Module.context, Attribute.context, Type.context, and Location.context back-references (facilitated testing and also on the TODO list).
* Adds method to create an empty Module.
* Discovered missing in npcomp.

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.
