[mlir][vector] Update the internal representation of in_bounds
This PR updates the internal representation of the `in_bounds` attribute for `xfer_read`/`xfer_write` Ops. Currently we use `ArrayAttr` - that's being updated to `DenseBoolArrayAttribute`. Note that this means that the asm format of the `xfer_{read|_write}` will change from: ```mlir vector.transfer_read %arg0[%0, %1], %cst {in_bounds = [true], permutation_map = #map3} : memref<12x16xf32>, vector<8xf32> ``` to: ```mlir vector.transfer_read %arg0[%0, %1], %cst {in_bounds = array<i1: true>, permutation_map = #map3} : memref<12x16xf32>, vector<8xf32> ```
