perf: use less defeq in frequently applied bv_decide simp rules (#8208) 
This PR reduces the need for defeq in frequently used bv_decide rewrite
by turning them into simprocs that work on structural equality instead.
As the intended meaning of these rewrites is to simply work with
structural equality anyways this should not change the proving power of
`bv_decide`'s rewriter but just make it faster on certain very large
problems.
