19655231 - [mlir][tensor] Add new builders for insert_slice/extract_slice Ops (nfc) (#169533)

[mlir][tensor] Add new builders for insert_slice/extract_slice Ops (nfc) (#169533) Adds new builders for `tensor.insert_slice` and `tensor.extract_slice` Ops for which the _offsets_ and the _strides_ are all 0s and 1s, respecitvely. This allows us to write: ```cpp // No offsets and no strides - implicitly set to 0s and 1s, // respectively. tensor::InsertSliceOp::create(rewriter, loc, src, dest, writeSizes); ``` instead of: ```cpp // Strides are initialised explicitly to 1s Attribute oneIdxAttr = rewriter.getIndexAttr(1); SmallVector<OpFoldResult> writeStrides(destRank, oneIdxAttr); // Offsets are initialised explicitly to 0s Attribute zeroIdxAttr = rewriter.getIndexAttr(0); SmallVector<OpFoldResult> writeOffsets(destRank, zeroIdxAttr); tensor::InsertSliceOp::create(rewriter, loc, src, dest, writeOffsets, writeSizes, writeStrides); ```
