Intel: Do not use GNU-like flags on Windows Refactor options out of `Modules/Compiler/Intel-{ASM,C,CXX,Fortran}.cmake` into a common helper in `Modules/Compiler/Intel.cmake`. Condition them to be used only on non-Windows hosts where the Intel compiler is GNU-like instead of MSVC-like. Previously this worked only because the options were later overridden by `Modules/Platform/Windows-Intel*.cmake`, but it is cleaner to not set the options in the first place.

include(Compiler/Intel)
__compiler_intel(C)
Split Intel compiler information files This moves platform-independent Intel compiler flags into separate "Compiler/Intel-<lang>.cmake" modules. Platform-specific flags are left untouched.

Ninja: Add dependencies on system-provided header files (#14914) When system-provided packages are upgraded we must re-compile sources depending on their headers. Use `-MD` instead of `-MMD` so that the generated depfiles do not exclude system headers. Suggested-by: Jussi Judin

set(CMAKE_C11_STANDARD_COMPILE_OPTION "${_std}=c11")
Intel-C: declare support for gnu11 Without extensions, functions like `strdup` are not available since they are actually controlled by feature flags such as _SVID_SOURCE and _BSD_SOURCE. When using `-std=c11` on Intel, none of these flags are set, so the functions are not declared properly leading to compile errors. Reported-by: Adam J. Stewart <ajstewart426@gmail.com> Closes: #16226

Factor an <INCLUDES> placeholder out of <FLAGS> in rule variables Teach the Makefile and Ninja generators to substitute for an <INCLUDES> placeholder instead of putting -I in <FLAGS>. Update our values for CMAKE_<LANG>_COMPILE_OBJECT, CMAKE_<LANG>_CREATE_ASSEMBLY_SOURCE, and CMAKE_<LANG>_CREATE_PREPROCESSED_SOURCE to place <INCLUDES> just before <FLAGS>.
