Examples Section for External Program Interfacing and other use cases

[radonnachie]

Is your feature request related to a problem? Please describe.
It took me a while to figure out how to link my c program to ghdl, and then to see what the limitations are. This is something that an example could have sped up, like this.

Describe the solution you'd like
I'd like to submit my personal MWEs to an examples page. A documentation page may be best. I hope then others will submit MWEs for other languages too.

I am asking for such a section to be made in the documentation, or to be told where to make such a page.

Describe alternatives you've considered
I considered an interfacing-examples sub folder, but then the repo would contain barely moderated code examples and possibly grow bloated.

Additional context
Such issues/questions as mine can then be passively answered. I think that the ratio of effort to gain is quite low - this would be easy and beneficial.

Duplication of #1059 essentially. Will just add to that thread.
