[BE] Add append_cxx_flag_if_supported macro (#82883)

Browse Source 
And use it throughout the CMakeLists and rectify `IF(APPLE)`/`IF(GNU_CXX_VERSION VERSION_GREATER A.B)` and so on

Also, add `target_compile_options_if_supported` and use it in `Dependencies.cmake` as well as in test's `CMakeListst.txt`

Delete `-Wno-unknown-warning-option` to test that conditions indeed working as expected
