  [mlir][affine] Add static basis support to affine.delinearize (#113846)

This commit makes `affine.delinealize` join other indexing operators,
like `vector.extract`, which store a mixed static/dynamic set of sizes,
offsets, or such. In this case, the `basis` (the set of values that will
be used to decompose the linear index) is now stored as an array of
index attributes where the basis is statically known, eliminating the
need to cretae constants.

This commit also adds copies of the delinearize utility in the affine
dialect to allow it to take an array of `OpFoldResult`s and extends te
DynamicIndexList parser/printer to allow specifying the delimiters in
tablegen (this is needed to avoid breaking existing syntax).
