docs/Makefile's debug echo used a space instead of a comma in $(call cxx_standard ...), so it always printed an empty standard. Every example was also compiled with -Wno-deprecated-declarations, which would silently hide an accidental deprecated-API call in any of them. Factor the duplicated compile flags into EXAMPLE_CPPFLAGS/ EXAMPLE_WARNFLAGS, build with -Werror=deprecated-declarations by default, and only allow the three examples that intentionally document deprecated API (the DEPRECATED_EXAMPLES list) to suppress it. Part of #5718 Signed-off-by: Niels Lohmann <mail@nlohmann.me>
