docs: generate nm-settings-docs-nmcli.xml based on nmcli meta data

We have the correct meta-data of supported properties for nmcli. It is
in clients/common. Use that for generating the manual page instead of
the properties that are part of libnm (some properties may be in libnm
but not supported by nmcli, or some properties may not be GObject
properties, and not detected as by GObject introspection).
