When writing the user-facing documentation, I noticed several inconsistencies
and asymmetries in the Python API we provide. Fix them by adding:
- the `owner` property to regions, similarly to blocks;
- the `isinstance` method to any class derived from `PyConcreteAttr`,
`PyConcreteValue` and `PyConreteAffineExpr`, similar to `PyConcreteType` to
enable `isa`-like calls without having to handle exceptions;
- a mechanism to create the first block in the region as we could only create
blocks relative to other blocks, with is impossible in an empty region.

This exposes creating a CallSiteLoc with a callee & list of frames for
callers. Follows the creation approach in C++ side where a list of
frames may be provided.

Provide a couple of quality-of-life usability improvements for Python bindings,
in particular:
* give access to the list of types for the list of op results or block
arguments, similarly to ValueRange->TypeRange,
* allow for constructing empty dictionary arrays,
* support construction of array attributes by concatenating an existing
attribute with a Python list of attributes.
All these are required for the upcoming customization of builtin and standard
ops.

Without this change, these attributes can only be accessed through the generic
operation attribute dictionary provided the caller knows the special operation
attribute names used for this purpose. Add some Python wrapping to support this
use case.
Also provide access to function arguments usable inside the function along with
a couple of quality-of-life improvements in using block arguments (function
arguments being the arguments of its entry block).

* ODS generated operations extend _OperationBase and without this, cannot be marshalled to CAPI functions.
* No test case updates: this kind of interop is quite hard to verify with in-tree tests.

* This allows multiple MLIR-API embedding downstreams to co-exist in the same process.

* It is pretty clear that no one has tried this yet since it was both incomplete and broken.
* Fixes a symbol hiding issues keeping even the generic builder from constructing an operation with successors.
* Adds ODS support for successors.
* Adds CAPI `mlirBlockGetParentRegion`, `mlirRegionEqual` + tests (and missing test for `mlirBlockGetParentOperation`).
* Adds Python property: `Block.region`.
* Adds Python methods: `Block.create_before` and `Block.create_after`.
* Adds Python property: `InsertionPoint.block`.
* Adds new blocks.py test to verify a plausible CFG construction case.

Historically the builtin dialect has had an empty namespace. This has unfortunately created a very awkward situation, where many utilities either have to special case the empty namespace, or just don't work at all right now. This revision adds a namespace to the builtin dialect, and starts to cleanup some of the utilities to no longer handle empty namespaces. For now, the assembly form of builtin operations does not require the `builtin.` prefix. (This should likely be re-evaluated though)

Adds `owner` python call to `mlir.ir.Value`.
Assuming that `PyValue.parentOperation` is intended to be the value's owner, this fixes the construction of it from `PyOpOperandList`.

* This makes them consistent with custom types/attributes, whose constructors will do a type checked conversion. Of course, the base classes can represent everything so never error.
* More importantly, this makes it possible to subclass Type and Attribute out of tree in sensible ways.

This adds `mlirOperationSetOperand` to the IR C API, similar to the

In the Python API, this adds `operands[index] = value` syntax, similar

Expose the debug flag as a readable and assignable property of a
dedicated class instead of a write-only function. Actually test the fact
of setting the flag. Move test to a dedicated file, it has zero relation
to context_managers.py where it was added.
Arguably, it should be promoted from mlir.ir to mlir module, but we are
not re-exporting the latter and this functionality is purposefully
hidden so can stay in IR for now. Drop unnecessary export code.
Refactor C API and put Debug into a separate library, fix it to actually
set the flag to the given value.
