Yukihiro "Matz" Matsumoto 0220ec2b62 mruby-bigint: add balance multiplication for asymmetric operands ...

When multiplying numbers where one is significantly larger than the other
(at least 2x size difference), split the larger number into chunks matching
the smaller number's size, multiply each chunk, and combine results. This
avoids pathological performance when Toom-3 pads asymmetric operands with
zeros.

Benchmarks show 6-16x speedup for size ratios from 10:1 to 40:1, with no
regression for symmetric cases.
