Introduce OtherSamples.kt to generate tables for writerside docs outside Korro

[koperagen]

Later, generated tables can be added anywhere. Example:

<dataFrame src="manual/extensionPropertiesApi1.html"/>

Thank you! Just what I needed for #635 :)
And indeed, for flexibility it's better to have the writerside styles separately like now, who knows what else we'll need it for.

I merged it to try it out with #635, and it seems to work great, aside from the scroll bars that are still visible. This might be due to resize-iframes.js, but I'll investigate it a little myself.

Edit: hmm, this might actually be normal behavior, since normally our tables aren't that wide.
