[mlir] Compose expand of collapse to cast (#172864)

In some cases `y = expand(collapse(x))` cannot be folded into x, since x
and y have different types.
In that case, we check if the two types are cast compatible.
If they are, it means the two types have compatible shape and layout and
y can be folded into cast(x).

This causes a change in memref::CastOp::areCastCompatible, where now a
dim of size 1 may have different strides.
