96848152fa udev: introduce NAMING_STABLE_VIRTUAL_MACS (retroactively)
This is for 6d36464065. It turns out that this is causing more problems than
expected. Let's retroactively introduce naming scheme v241 to conditionalize
this change.

Follow-up for #12792 and 6d36464065. See also
https://bugzilla.suse.com/show_bug.cgi?id=1136600.

2ebe027b44 man: clean up naming scheme description a bit
This is in preparation for later changes.  Let's change the documentation of
net.naming-scheme= to also say that it applies to MAC addresses. This commit
doesn't actually implement that though.

8c053c83ae udev: drop "en" prefix from ID_NET_NAME_ONBOARD
The comment in udev-builtin-net_id.c (removed in grandparent commit) showed the
property without the prefix. I assume that was always the intent, because it
doesn't make much sense to concatenate anything to an arbitrary user-specified
field.

0b1e5b6ed8 man: describe naming schemes in a new man page
I decided to make this a separate man page because it is freakin' long.
This content could equally well go in systemd-udevd.service(8), systemd.link(5),
or a new man page for the net_id builtin.

v2:
- rename to systemd.net-naming-scheme
- add udevadm test-builtin net_id example
