printf: make negative values wrap around with unsigned/hex format

To convert from negative to unsigned with overflow, we get the two's complement
representation of the absolute (unsigned) value.

uucore: format: Fix hexadecimal default format print
...
The default hex format, on x86(-64) prints 15 digits after the
decimal point, _but_ also trims trailing zeros, so it's not just
a simple default precision and a little bit of extra handling is
required.
Also add a bunch of tests.
Fixes #7364 .

uucore: format: num_parser: Add value to Overflow error
...
When parsing integers, we should still return the min/max value
of the type (depending on the type), and wrap that in the error.
We need to refactor the map function to handle this case better,
and add an extract function to get the value out of an error
(if any).
This fixes the integer part of #7508 .

printf: error on missing hexadecial escape value
...
Change `printf` to correctly terminate with an error message when an
escape sequence starts with `\x` but doesn't include a literal
hexadecimal value after. For example, before this commit,
printf '\x'
would output `\x`, but after this commit, it terminates with an error
message,
printf: missing hexadecimal number in escape
Fixes #7097
