This patch introduces pattern rewrites for reducing the rank of named linalg contraction ops with unit spatial dim(s) to other named contraction ops. For example `linalg.batch_matmul` with batch size 1 -> `linalg.matmul` and `linalg.matmul` with unit LHS spatial dim -> `linalg.vecmat`, etc. These patterns don't support reducing the rank along reduction dimension as those don't convert to other named contraction ops.
