[libc] Fix implicit conversion error on rv32 (#138622)

This patch fixes the following error on rv32 (and possibly other 32-bit
archs):

FPBits.h:760:40: error: implicit conversion loses integer precision:
'int' to 'size_t' (aka 'unsigned int')
[-Werror,-Wimplicit-int-conversion]
  760 |       result.set_significand(number >> -ep);

Fixes #138425.
