[mlir] NFC - Expose an OffsetSizeAndStrideOpInterface
This revision will make it easier to create new ops base on the strided memref abstraction outside of the std dialect. OffsetSizeAndStrideOpInterface is an interface for ops that allow specifying mixed dynamic and static offsets, sizes and strides variadic operands. Ops that implement this interface need to expose the following methods: 1. `getArrayAttrRanks` to specify the length of static integer attributes. 2. `offsets`, `sizes` and `strides` variadic operands. 3. `static_offsets`, resp. `static_sizes` and `static_strides` integer array attributes. The invariants of this interface are: 1. `static_offsets`, `static_sizes` and `static_strides` have length exactly `getArrayAttrRanks()`[0] (resp. [1], [2]). 2. `offsets`, `sizes` and `strides` have each length at most `getArrayAttrRanks()`[0] (resp. [1], [2]). 3. if an entry of `static_offsets` (resp. `static_sizes`, `static_strides`) is equal to a special sentinel value, namely `ShapedType::kDynamicStrideOrOffset` (resp. `ShapedType::kDynamicSize`, `ShapedType::kDynamicStrideOrOffset`), then the corresponding entry is a dynamic offset (resp. size, stride). 4. a variadic `offset` (resp. `sizes`, `strides`) operand must be present for each dynamic offset (resp. size, stride). This interface is useful to factor out common behavior and provide support for carrying or injecting static behavior through the use of the static attributes.
