Use filename as id/class prefix. (#16997) (#17000)

Browse source 
Currently the svg minifier (`make svg`) rewrites all `id` and `class` attributes in svg files. Every file gets the ids `a, b, ...`. If multiple svgs with ids are used on a page these ids are conflicting and the results are broken images.

| minified ids | unique ids |
| - | - |

This PR adds a prefix (the filename) to every id/class.

Follow up problem: Because we embed svg images there are duplicated ids if one svg image is used multiple times on a page. As those ids refer to the same content it may be no real problem because browser handle that fine.
