When using `-D_CURL_TESTS_CONCAT=ON` with CMake, do not concatenate `first.h` (or any future header) into the output C file, but `#include` it instead. This is to play nice with compilers and analyzers which may apply different checker rules on logic found in headers, vs. the input source file. As seen for example with `-Wunused-macro` enabled in CI. After this patch concatenated sources behave closer to regular C sources. Also: - first.h: drop some `-Wunused-macro` silencers that became redundant with this patch. Follow-up to47f411c6d8#21554 Follow-up to39542f0993#20667 Closes #21656
