  [mlir][tblgen] Add additional constructor to Adaptor class

Add an additional adaptor constructor that copies everything except for the values. These are provided with by a second parameter.

This commit is in preparation of merging the 1:1 and 1:N dialect conversions. As part of that, a new `matchAndRewrite` function is added. For details, see this RFC: https://discourse.llvm.org/t/rfc-merging-1-1-and-1-n-dialect-conversions/82513

```c++
template <typename SourceOp>
class OpConversionPattern : public ConversionPattern {
 public:
  virtual LogicalResult
  matchAndRewrite(SourceOp op, OneToNOpAdaptor adaptor,
                  ConversionPatternRewriter &rewriter) const {
    SmallVector<Value> oneToOneOperands =
        getOneToOneAdaptorOperands(adaptor.getOperands());

    // This OpAdaptor constructor is added by this commit.
    return matchAndRewrite(op, OpAdaptor(oneToOneOperands, adaptor), rewriter);
  }
};
```
