Add target_compile_features command. This can be used to set the compiler features required by particular targets. An error is issued at CMake time if the compiler does not support the required feature. If a language dialect flag is required by the features used, that will be added automatically. Base the target_compile_features command on cmTargetPropCommandBase. This gives us 'free' handling of IMPORTED, ALIAS, INTERFACE, non-compilable and missing targets.

project(target_compile_features)
Features: Extend concept to C language. Add properties and variables corresponding to CXX equivalents. Add features for c_function_prototypes (C90), c_restrict (C99), c_variadic_macros (C99) and c_static_assert (C11). This feature set can be extended later. Add a <PREFIX>_RESTRICT symbol define to WriteCompilerDetectionHeader to conditionally represent the c_restrict feature.

if (NOT CMAKE_CXX_COMPILE_FEATURES AND NOT CMAKE_C_COMPILE_FEATURES)
Tests: Execute compile features tests unconditionally. Conditionally create a dummy test if there are no known features.
