Niels Lohmann 23febcee51 Merge duplicate byte-to-hex helper and drop stale '| 0' promotions ...

serializer::hex_bytes() and binary_writer::hex_byte() had identical
bodies. Keep one, detail::hex_byte() in string_utils.hpp, and use it
from both. Also drop the `| 0` at the two serializer call sites
(hex_bytes(byte | 0) and hex_bytes(s.back() | 0)): #3088 (7440786b8)
added it so that `ss << std::hex << (byte | 0)` printed a number
rather than a char with the old stringstream writer; the int result
just narrows back to uint8_t now, so it was a no-op.

Behavior is unchanged: unit-serialization, unit-bon8 (whose
type_error.316 messages exercise this code) and unit-diagnostics
pass, and both headers still compile standalone with -Werror.

Part of #5709
