Fix for bug#10798. VS10 did not append -I flags with COMPILE_FLAGS prop. This fix adds a test for this case for all generators.

Add the INTERFACE_SYSTEM_INCLUDE_DIRECTORIES target property. Unlike other target properties, this does not have a corresponding non-INTERFACE variant. This allows propagation of system attribute on include directories from link dependents.

Clang: Add separate "AppleClang" compiler id Apple distributes their own Clang build with their own version numbers that differ from upstream Clang. Use the __apple_build_version__ symbol to identify the Apple Clang compiler and report the Apple Build Version as the fourth version component in CMAKE_<LANG>_COMPILER_VERSION. Add Compiler/AppleClang-<lang> and Platform/Darwin-AppleClang-<lang> modules that simply include the upstream equivalents. Fix comparisons of CMAKE_<LANG>_COMPILER_ID to Clang in CMake's own source and tests to account for AppleClang.

Revert "Xcode: Obey SYSTEM keyword for includes (#15687)" Revert commit v3.7.0-rc1~266^2 (Xcode: Obey SYSTEM keyword for includes, 2015-08-31). It worked for C, C++, and Swift but not for GNU Assembly files for which Xcode has no property to set flags. Closes: #16449

Extract and use the INCLUDE_DIRECTORIES target properties. Eliminate callers of cmMakefile::GetIncludeDirectories. All callers of GetIncludeDirectories should go through the local generator object. Only the local generator calls cmTarget::GetIncludeDirectories directly.

Add a variable to specify language-wide system include directories Create a `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES` variable to specify system include directories for for `<LANG>` compiler command lines. This plays a role for include directories as the existing `CMAKE_<LANG>_STANDARD_LIBRARIES` variable does for link libraries.
