libnm: add internal header file "nm-core-types-internal.h"

This shall contain type definitions, with similar use
to "nm-core-internal.h".

However, it should contain a minimal set, so that we can include this
header in other headers under "src/", without including the whole
"nm-core-internal.h" in headers.
