[Tagging] New tag proposal: 'addr=milestone'

This tag only comes to give a standard to something that already is
being mapped off the cuff. When you search by "KM" in
https://taginfo.openstreetmap.org/keys/addr:housenumber#values you
will find 2758 addr:housenumber that contains "KM" as part of their
values. Such information can be even found in addr:street itself. The
string "KM " is found 3025 times as part of the value of addr:street
(https://taginfo.openstreetmap.org/keys/addr:street#values), and 1864
times as part of addr:full
(https://taginfo.openstreetmap.org/keys/addr:full#values). And who
knows how many times people didn't add this information just why they
couldn't find a specific tag for it.

I am not sure about to keep "Km". It might be understandable by the
key 'addr:milestone' itself. However, a reason to keep "Km" and "Mi"
as a prefix would be to differentiate each other. Anyways I think that
"." must go according to the "International System of Units".

I don't know if such examples could be easily found as images.
Although this is a very common situation in Brazil, it's rare when
people print it in the facade of a building, for example. As an
example of an image, that I personally know, I can present this
(https://imgur.com/a/qxiBmOo) that stands for this
(https://www.openstreetmap.org/way/376981766). The image is not good
enough but it's printed "Av. Pref. Evandro Behr | Km 8 . Nº 7921".
I can present to you guys how many examples of links as you want. I
could say that most of the POIs at highways in rural areas have
milestone as part of their address. Some examples in Brazil:

As in Brazil, it's widely used in rural areas, they are in public
records as well. They are used many times even there is a determined
value to addr:housenumber, so 'addr:milestone' could be used with or
without 'addr:housenumber', and always with 'addr:street'.
