60335441 - [mlir][linalg] Fix memref type verification in CollapseLinalgDimensions (#147245)

[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.
