Apply CSP rules for onlyoffice and richdocuments

[kulmann]

Description

The iframe integrations of the documentserver coming from onlyoffice / richdocuments need certain CSP rules. With this PR we're extracting the respective documentserver domains from the two apps. We'll work on a generic solution when it becomes relevant.

Motivation and Context

Enable onlyoffice to build an integration of their documentserver into a web extension.
