This commit: - Introduces a new `InParallelOpInterface`, along with the `ParallelCombiningOpInterface`, represent the parallel updating operations we have in a parallel loop of `scf.forall`. - Change the name of `ParallelCombiningOpInterface` to `InParallelOpInterface` as the naming was quite confusing. - `ParallelCombiningOpInterface` now is used to generalize operations that insert into shared tensors within parallel combining regions. Previously, only `tensor.parallel_insert_slice` was supported directly in `scf.InParallelOp` regions. - `tensor.parallel_insert_slice` now implements `ParallelCombiningOpInterface`. This change enables future extensions to support additional parallel combining operations beyond `tensor.parallel_insert_slice`, which have different update semantics, so the `in_parallel` region can correctly and safely represent these kinds of operation without potential mistakes such as races.
