  [mlir][linalg] Fix memref type verification in CollapseLinalgDimensions (#147245)

When collapsing linalg dimensions we check if its memref operands are
guaranteed to be collapsible. However, we currently assume that the
matching indexing map is the identity map.

This commit modifies this behavior and checks if the memref is
collapsible on the transformed dimensions.
