This PR packages the current `scf.unroll` rewrite rules into a pass to be used to try and unroll the scf. The usage: ```python from kirin. passes.aggressive import UnrollScf UnrollScf(dialects).fixpoint(method) ``` For a single application, this pass unrolls the top-level of scf nodes in the method body. Therefore, to unroll nested SCF you must apply this in a fixpoint way. The modification if removing `terminate` in the UnrollFor rewrite rule fixes issue #475 because now this Pass fixpoint should be over the depth of the nesting, not the number of iterations.
