Add TDE_CXX_COMPILE_STDCXX macro to check and enforce C++ standard.v3.5.13-sru

The macro is a simplified form of AX_CXX_COMPILE_STDCXX from autoconf.
To verify the C++ standard supported by the compiler, only the value
of the __cplusplus constant defined by the compiler is checked,
instead of testing examples of using individual C++ features.
