Dan Klishch 80517b5a70 AK: Use helpers from BigIntBase.h in MinimalBigInt ...

Although it might seem like we've switched to more generic functions,
which must run slower, it is not the case. The time required to parse
"1", for example, decreased by 1%. For numbers with more digits, the
effect is more noticeable: 8-digit numbers are parsed ~5% faster; for
gigantic 750-digit numbers, parsing is 2 times faster.

The later result is achieved by using UFixedBigInt<64>::wide_multiply
instead of u128::operator*(u128).
