[mlir][Linalg] Reimplement and extend getStridesAndOffset
Summary: This diff reimplements getStridesAndOffset in a significantly
simpler way by operating on the AffineExpr and calling into
simplifyAffineExpr instead of rolling its own saturating arithmetic.
As a consequence it becomes quite simple to extend the behavior of
getStridesAndOffset to encompass more cases by manipulating the
AffineExpr more directly. The divisions are still filtered out and
continue to yield fully dynamic strides. Simplifying the divisions is
left for a later time if compelling use cases arise.
Relevant tests are added.
