Updated CMakeLists.txt to compile Google Highway in C++17 mode by default if CMAKE_CXX_STANDARD is not set and the C++ compiler supports C++17 mode.

With the changes made to CMakeLists.txt in this pull request, Google Highway will still be compiled in C++11 mode if CMAKE_CXX_STANDARD is set to 11 and Google Highway will still be compiled in C++14 mode if CMAKE_CXX_STANDARD is set to 14.
