We want to use these defines for option names also in "shared/nm-base" (and in turn in "shared/nm-platform), which cannot include "libnm-core". However, they are also public API of libnm. To get this done, in a first step, move these defines to a new header "libnm-core/nm-ethtool-utils.h". Since now the name "nm-ethtool-utils.h" is taken, also rename nm-libnm-core-intern files.
