This is an ongoing series of commits that are reformatting our
Python code.
Reformatting is done with `black`.
If you end up having problems merging this commit because you
have made changes to a python file, the best way to handle that
is to run git checkout --ours <yourfile> and then reformat it
with black.
If you run into any problems, post to discourse about it and
we will try to help.

This adds a simple PyOpOperand based on MlirOpOperand, which can has
properties for the owner op and operation number.
This also adds a PyOpOperandIterator that defines methods for __iter__
and __next__ so PyOpOperands can be iterated over using the the
MlirOpOperand C API.
Finally, a uses psuedo-container is added to PyValue so the uses can
generically be iterated.

Previously, calling `Value.owner()` would C++ assert in debug builds if
`Value` was a block argument. Additionally, the behavior was just wrong
in release builds. This patch adds support for BlockArg Values.
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.

* NFC but has some fixes for CMake glitches discovered along the way (things not cleaning properly, co-mingled depends).
* Includes previously unsubmitted fix in D98681 and a TODO to fix it more appropriately in a smaller followup.
