Niels Lohmann 668fddc766 Drop serializer.hpp's dependency on binary_writer.hpp ...

The only use of binary_writer in serializer.hpp was
binary_writer<BasicJsonType, char>::to_char_type() to write the
U+FFFD replacement character's three bytes. With CharType=char this
is an identity conversion, so the include of binary_writer.hpp (and
transitively binary_reader.hpp) pulled in a large, unrelated header
for a no-op call.

Write the three bytes directly instead. serializer.hpp compiles
standalone with -Wall -Wextra -Werror, with and without
-funsigned-char, and unit-serialization's error_handler_t::replace
cases (with and without ensure_ascii) still pass. Moving
binary_writer's to_char_type/to_msgpack_length to its private section
is left as an optional follow-up.

Part of #5709
