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.

As discussed on discord, we have never actually been able to build with the project-wide published min version of 3.14.3. The buildbot that tests the Python configuration is currently pinned to 3.19.1, and there are a number of non-version/policy controlled features that Python building relies on that makes it unreliable with older versions. Some of the issues are pretty fundamental and I don't know how to do them on the older version. I think that, as an optional feature, at least advertising the PSA as in this patch is a good middle ground until the next project-wide CMake version bump.
Also moves setup logic to a macro so that everyone can use it.

By doing so, it is not necessary to get the OpOperand a second time via
getAliasingOpOperand. Also, code slightly more readable because we do
not have to deal with Optional<> return value.

we compute the reduction and then combine it with the original value.

This patch teaches `isProjectedPermutation` and `inverseAndBroadcastProjectedPermutation`
utilities to deal with maps representing an explicit broadcast, e.g., (d0, d1) -> (d0, 0).
This extension is needed to enable vectorization of such explicit broadcast in Linalg.

This revision updates the op semantics, printer, parser and verifier to allow 0-d transfers.
Until 0-d vectors are available, such transfers have a special form that transits through vector<1xt>.
This is a stepping stone towards the longer term work of adding 0-d vectors and will help significantly reduce corner cases in vectorization.
Transformations and lowerings do not yet support this form, extensions will follow.

vector.multi_reduction currently does not allow reducing down to a scalar.
This creates corner cases that are hard to handle during vectorization.
This revision extends the semantics and adds the proper transforms, lowerings and canonicalizations to allow lowering out of vector.multi_reduction to other abstractions all the way to LLVM.
In a future, where we will also allow 0-d vectors, scalars will still be relevant: 0-d vector and scalars are not equivalent on all hardware.
In the process, splice out the implementation patterns related to vector.multi_reduce into a new file.
