[libc] add fuzz target for strtointeger functions
...
The string to integer conversion functions are well suited to
differential fuzzing, and this patch adds a target to enable just that.
It also fixes a bug in the fuzzing comparison logic and changes atoi
slightly to match the behavior described in the C standard.

[libc] add atof, strtof and strtod
...
Add the string to floating point conversion functions.
Long doubles aren't supported yet, but floats and doubles are. The
primary algorithm used is the Eisel-Lemire ParseNumberF64 algorithm,
with the Simple Decimal Conversion algorithm as backup.
