  [mlir][memref] Fix index delinearization for CollapseShapeOp folding (#68833)

The `resolveSourceIndicesCollapseShape` method is used to compute
indices into the source `MemRef` of a `CollapseShapeOp` from the
collapsed indices. This method didn't check for dynamic sizes of the
source shape which led to a crash.
