Clean up core:math/big
...
- Deprecate the u64/u32 implementation so we can use fewer nails and have an easier time of maintaining and optimizing the package going forward. The remaining implementation still works on 32-bit targets, it's just a smidge less efficient.
- Use only 1 nail instead of 4. The tests now run 3.5% faster as a result.
Future optimizations may including using fully packed backing (no nails) using `intrinsics.overflow_*` to handle borrow and carry safely.

Speed up big.itoa
...
Extract 18 (64-bit) or 8 (32-bit) digits per big division.
This gives a 2.5x speedup for a 1024-bit bigint.

Turn core:math/bìg tests into regular core:testing tests.
...
`core:math/big` has been verified against Python's big integer implementation long enough.
Turn it into a regular regression test using the `core:testing` framework, testing against
a generated corpus of test vectors.

Fix a range check in int_atoi in core:math/big.
...
The check seems to have been assuming that rune comparisons are
unsigned, but they're signed. This was causing an assertion failure for
certain input characters (anything with an ASCII value less than
'+'/43).
