Niels Lohmann 809ace26b3 Keep writing ill-formed UTF-8 unchanged unless JSON_STRICT_BINARY_UTF8 is set

Throwing type_error.316 from to_cbor(), to_ubjson(), to_bjdata(), and
to_bson() by default would break code that works with 3.12.0, for example
code that stores ISO 8859-1 in a string and only writes it to a binary
format. Following the plan for 4.0.0, the check is now opt-in via the new
macro JSON_STRICT_BINARY_UTF8 (default 0), which is planned to become the
default in 4.0.0:

- abi_macros.hpp: default 0 and ABI tag _sbu8; macro_unscope.hpp undefines
  it; CMake option JSON_StrictBinaryUTF8; ABI namespace tests updated.
- binary_writer: the four writers call check_text_utf8(), which checks
  only if the macro is enabled. BON8 always checks, MessagePack never.
- Tests: the strict checks move to unit-binary_utf8_strict.cpp, which
  defines the macro; the per-format tests now check that the default
  writes the bytes unchanged (from_X(to_X(j)) == j).
- Docs: new macro page, macro lists, CMake option, namespace tags, and the
  writer/format pages describe the default and the opt-in.
