donald chen 889b67c9d3 [mlir] [memref] add more checks to the memref.reinterpret_cast (#112669) ...

Operation memref.reinterpret_cast was accept input like:

%out = memref.reinterpret_cast %in to offset: [%offset], sizes: [10],
strides: [1]
         : memref<?xf32> to memref<10xf32>

A problem arises: while lowering, the true offset of %out is %offset,
but its data type indicates an offset of 0. Permitting this
inconsistency can result in incorrect outcomes, as certain pass might
erroneously extract the offset from the data type of %out.

This patch fixes this by enforcing that the return value's data type
aligns
with the input parameter.
