[IMP] im_livechat,web: use nicer placeholders for livechat

In the context of a livechat session, a placeholder that looks like a
person is better than a generic "missing picture" one, when the user has
no public avatar.

In order to allow a different placeholder without exposing a public
placeholder parameter, a separate route is introduced for the
purpose of displaying user avatars:
/web/partner_image/<id>/<field>/<model>
and can be simplified to:
/web/partner_image/<id> for loading a partner avatar (`image_small`).

The common part of the /web/image route was moved into a helper
function that is not directly exposed.

Task-ID 1924666
Closes #32664
