Generate doc from PHP

[mvorisek]

If the doc can not be kept up-to-date, it is useless and should be reduced/removed or self-generated from the actual code - and I prefer it.

I personally use PHP source as doc directly.

• generate the doc for web-only, ie. remove it from repo
• do it for all repos

possible tools can be https://github.com/code-lts/doctum or https://github.com/ApiGen/ApiGen

@abbadon1334 would be nice if you can generate the docs from code and publish on agiletoolkit.org web, at least for atk4/core, data and ui
