Build: Use zm-* interfaces to set cxx standard and warning flags

INTERFACE
build: Enable Wextra with some exceptions -Wno-cast-function-type: Signal handler code relies on this. -Wno-type-limits: Some of the color space conversion code in zm_image throws this warning. To not break anything let's ignore this warning for the time being. Note that clang enables -Woverloaded-virtual with -Wextra. To not flood the GCC build log with warnings let's not enable this at the moment. This will be done in a second step, when the currently throwing code will be cleaned up.
