project: Add infrastructure for recording CXX compiler features Add a feature test using the compiler macros and the preprocessor to determine available features. Add a CMAKE_CXX_COMPILE_FEATURES variable which contains all features known to the loaded compiler, and a CMAKE_CXX_KNOWN_FEATURES variable containing all features known to CMake. Add language standard specific variables for internal use to determine the standard-specific compile flags to use. This will be extended to other languages in the future. Follow-up commits will add features which will be recorded by the feature test.

CMAKE_CXX_COMPILE_FEATURES
--------------------------
List of features known to the C++ compiler
These features are known to be available for use with the C++ compiler. This
Features: Make CMAKE_CXX_KNOWN_FEATURES a property. As a 'built-in' variable it imposes a cost on all variable lookups and it is expected to be rarely used.

list is a subset of the features listed in the :prop_gbl:`CMAKE_CXX_KNOWN_FEATURES`
global property.
Help: Add a manual for compiler feature control. Link to it from the documentation of related properties, variables and commands. Extend the cmake-developer(7) documentation with notes on extending feature support for compilers.
