This PR moves the `iframe` logic into a macro, so that `videos.html` and `general.html` both can benefit from the workaround to fix YouTube results by @return42 in https://github.com/searxng/searxng/pull/5858
It also fixes that only YouTube videos contained the closing `>` after `<iframe border="0" ...`, the regression has been caused by https://github.com/searxng/searxng/pull/5858
## Why is this change important?
Currently, the page breaks if there's any non-YouTube Iframe
Here, the page ends in the middle of the results and the footer and page number selector are not visible.
This PR adds a new result type: File
Python class: searx/result_types/file.py
Jinja template: searx/templates/simple/result_templates/file.html
CSS (less) client/simple/src/less/result_types/file.less
Class 'File' (singular) replaces template 'files.html' (plural). The renaming
was carried out because there is only one file (singular) in a result. Not to be
confused with the category 'files' where in multiple results can exist.
As mentioned in issue [1], the class '.category-files' was removed from the CSS
and the stylesheet was adopted in result_types/file.less (there based on the
templates and no longer based on the category).

Embedded HTML breaks SearXNG architecture. To modularize, HTML is generated in
the templates (oscar & simple) and result parameter 'embedded' is replaced by
'data_src' (and 'audio_src'), an URL for embedded content (<iframe>).
