Support CiviCRM APIv4

[jensschuppe]

With CiviMRF/CMRF_Abstract_Core#18, this introduces support for CiviCRM APIv4 and partly resolves #57 (leaving out the Webform integration for now).

This will be backwards-compatible so that it can be released within the 2.x major version branch.

• Adds entity and action columns to the civicrm_api_call table (via the adapted schema provided by CiviMRF/CMRF_Abstract_Core) via a hook_update_N() implementation
• Adjusts the call report view and single displays according to the above schema change (in the provided optional config, but does not update it)
• Extends the CMRFDataset configuration entity with an api_version property, which is configurable per CiviMRF Views Dataset
• Adjusts getfields calls for the new structure those calls return with APIv4 in the CMRFViews controller
• Adds an API4 (civicrm_api4) Views query plugin for APIv4 Datasets
• Extends the CMRFProfile configuration entity with an urlV4 property, which is configurable per CiviMRF Profile
• Does some refactoring of the Call implementation

The code in https://github.com/CiviMRF/cmrf_core/blob/dc975770bf36b7a9a609d1211da9b6aa68f42e29/cmrf_views/src/CMRFViews.php#L304 is only relevant for APIv3 and the index in the first check should be type as well and probably isset instead of empty.

I'm not sure whether File fields contain their URLs only with APIv4 or that changed for APIv3 as well (the File field handler in CiviMRF Views expects a CiviCRM Attachment entity ID instead), but downloading the file and displaying it with this handler might not work because of permission restrictions in CiviCRM, at least for some file fields. So this isn't fully working.

This will be available with a 2.1.x version of the module.
