```
math.big.int: document the purpose of limb_len in scalar methods

Ideally this duplicated code could be factored out into a function, but
there doesn't seem to be any way in the Zig type system to represent an
argument to a function called at comptime that is only needed if it is
comptime-known.  Instead, we document what is going on in an adjacent
comment in case it gets copy-pasted into new methods in the future.
