Remove patterns that fold tensor subset ops into vector transfer ops from the vector dialect. These patterns already exist in the tensor dialect.

* Remove `transform::PatternRegistry`.
* Add a new op for each currently registered pattern set.
* Change names of vector dialect pattern selector ops, so that they are consistent with the remaining code base.
* Remove redundant `transform.vector.extract_address_computations` op.

This gives us better control to lower masked operations independently of the create mask operations.
It is often useful to maintain high-level mask information instead of lowering it too early to
too fine-grained form.

This revision adds vector transform operations that allow us to better inspect the composition
of various lowerings that were previously very opaque.
This commit is NFC in that it does not change patterns beyond adding `rewriter.notifyFailure` messages
and it does not change the tests beyond breaking them into pieces and using transforms instead of
throwaway opaque test passes.

Vector dialect patterns have grown enormously in the past year to a point where they are now impenetrable.
Start reorganizing them towards finer-grained control.

Refactor the definition of the enums that are used in the lower_vectors
operation of the transformation dialect.
This avoid duplicating the definition of all the configurations that
this operation can trigger.

This patch is part of a larger simplification effort of vector transfer
operations. It removes the flag `lower-permutation-maps` from
VectorToSCF conversion and enables the lowering of permutation maps
by default. This means that VectorToSCF will always lower permutation
maps to independent broadcast/transpose operations before lowering
vector operations to SCF.

This op significantly improves transfor dialect usage when using vector abstractions.
It also brings us closer to writing simple end-to-end unit tests that guard against subtle regressions in how patterns combine.
