Yukihiro "Matz" Matsumoto 14d1ad0038 mruby-bigint: remove broken MSVC _umul128 optimization path ...

The MSVC _umul128 code path was designed for 64-bit limbs but mruby's
bigint implementation uses 32-bit limbs even on 64-bit builds. This
fundamental mismatch caused incorrect bigint calculations on VC 64-bit
builds, producing results like "100000000000000000000" -> "1661992960".

Removed the MSVC optimization to fall back to the portable double-limb
arithmetic which correctly handles 32-bit limbs.
