Niels Lohmann 35a3b0f3de Deduplicate the MessagePack unsigned-integer writer ladder ...

The number_integer (non-negative branch) and number_unsigned cases in
write_msgpack() each held their own copy of the fixint/uint8/16/32/64
ladder, kept in lockstep only by a comment ("we used the code from the
value_t::number_unsigned case here"). Both copies mixed union members:
the signed copy compared number_unsigned but wrote number_integer, and
vice versa.

Extract write_msgpack_unsigned(std::uint64_t), mirroring how
write_cbor_head() already avoids the same duplication for CBOR, and
call it from both cases. Each case now reads only its own active
union member. Output bytes are unchanged for the default 64-bit
number types.
