Consistently place C++ use of extern "C" after all include directives, within the negative branch of _ASMLANGUAGE if used. The inclusion of the generated syscall files is placed outside the extern "C" block as the generated file has its own extern "C" block. Background from issue #17997: Declarations that use C linkage should be placed within extern "C" so the language linkage is correct when the header is included by a C++ compiler. Similarly #include directives should be outside the extern "C" to ensure the language-specific default linkage is applied to any declarations provided by the included header.
