I can not find anywhere we use the logo-*.png files currently in the
gitea public directory. Remove these as they're all trivially
re-created via the SVG if we find we want them.
Similarly I don't see anywhere we use "opendev-icon.svg"; it is the
same as "logo.svg". This is removed.
Move the logo with text "opendev.svg" into the assets bundle (only
user of this I can find is paste.opendev.org).
Also move in the favicon.<png/svg> files
Note all these are copied back into the gitea container at the same
location so nothing will break. However we wish to have the
identified external users not rely on files served as gitea assets as
the new version of gitea will move them.

Move some common assets into a top-level assets/ directory. Services
can reference these assets via
https://opendev.org/opendev/system-config/raw/branch/master/assets/<file>
in <img> tags, etc.
Some services want to embed these into their images, but we wish to
only keep one canonical copy. For this, add a Dockerfile and jobs
that creates a simple bundle of assets in opendevorg/assets. This can
be referenced in other builds; the new BuildKit bind-mount is
particularly useful for this
(c.f. I36bdc76471eec5380a676ebcdd885a88d3985976).
