Add "Create Documents" SearchKit action

[dontub]

This PR adds a SearchKit action for creating documents with CiviOffice. It can be easily adopted for other extensions. The action redirects to the web-based queue-runner as it is done for the legacy action. (See todo in RenderWebAction for how to improve it.)

To use the action it is required to have the access CiviCRM. (Should we have a special permission?) The entities to render are limited to those the user can get the ID for, if permission check is not disabled.

Other notable changes include:

• Various readonly APIv4 actions.
• Entities types given to the CiviOffice.convert API have to be in the actual case (Contact instead of contact). Using the previous ones will trigger a deprecation error.
• Queue building is refactored to be usable from two places.
• Civi token context generation is refactored. (Using the CiviOffice token event.)
• APIv4 permission checks are disabled for token context generation. (If document generation is allowed than token generation must not fail. It could be considered to not add all related entities.)
• phpcs, phpstan, phpunit in GitHub workflow. (phpcs and phpstan is currently to the Civi and tests directory.)
