Mike Urbach 63d16d06f5 [mlir] Support setting operand values in C and Python APIs.
This adds `mlirOperationSetOperand` to the IR C API, similar to the
function to get an operand.

In the Python API, this adds `operands[index] = value` syntax, similar
to the syntax to get an operand with `operands[index]`.

Stella Laurenzo 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).

zhanghb97 5f0c1e3806 [mlir][Python] Sync Python bindings with C API MlirStringRef modification.
MLIR C API use the `MlirStringRef` instead of `const char *` for the string type now. This patch sync the Python bindings with the C API modification.

Alex Zinenko 6c7e6b2c9a [mlir] Support slicing for operands in results in Python bindings
Slicing, that is element access with `[being🔚step]` structure, is
a common Python idiom for sequence-like containers. It is also necessary
to support custom accessor for operations with variadic operands and
results (an operation an return a slice of its operands that correspond
to the given variadic group).

Add generic utility to support slicing in Python bindings and use it
for operation operands and results.

Stella Laurenzo af66cd173f [mlir][Python] Context managers for Context, InsertionPoint, Location.
* Finishes support for Context, InsertionPoint and Location to be carried by the thread using context managers.
* Introduces type casters and utilities so that DefaultPyMlirContext and DefaultPyLocation in method signatures does the right thing (allows explicit or gets from the thread context).
* Extend the rules for the thread context stack to handle nesting, appropriately inheriting and clearing depending on whether the context is the same.
* Refactors all method signatures to follow the new convention on trailing parameters for defaulting parameters (loc, ip, context). When the objects are carried in the thread context, this allows most explicit uses of these values to be elided.
* Removes the style guide section on putting accessors to construct global objects on the PyMlirContext: this style fails to make good use of the new facility since it is often the only thing remaining needing an MlirContext.
* Moves Module parse/creation from mlir.ir.Context to static methods on mlir.ir.Module.
* Moves Context.create_operation to a static Operation.create method.
* Moves Type parsing from mlir.ir.Context to static methods on mlir.ir.Type.
* Moves Attribute parsing from mlir.ir.Context to static methods on mlir.ir.Attribute.
* Move Location factory methods from mlir.ir.Context to static methods on mlir.ir.Location.
* Refactors the std dialect fake "ODS" generated code to take advantage of the new scheme.

Stella Laurenzo c1ded6a759 Add mlir python APIs for creating operations, regions and blocks.
* The API is a bit more verbose than I feel like it needs to be. In a follow-up I'd like to abbreviate some things and look in to creating aliases for common accessors.
* There is a lingering lifetime hazard between the module and newly added operations. We have the facilities now to solve for this but I will do that in a follow-up.
* We may need to craft a more limited API for safely referencing successors when creating operations. We need more facilities to really prove that out and should defer for now.

Stella Laurenzo 2d1362e09a Add Location, Region and Block to MLIR Python bindings.
* This is just enough to create regions/blocks and iterate over them.
* Does not yet implement the preferred iteration strategy (python pseudo containers).
* Refinements need to come after doing basic mappings of operations and values so that the whole hierarchy can be used.
