AK: Remove strtoull dependency from format.
This function is not avaliable in the kernel. In the future it would be nice to have some sort of <charconv> header that does this for all integer types and then call it in strtoull and et cetera. The difference would be that this function say 'from_chars' would return an Optional and not just interpret anything invalid as zero.
