= Make pkexec and pkla-compat optional

Detailed Description
pkexec and pkla-compat (package) are legacy tools that are no longer needed on a desktop and increase the attack surface as they are SetUID binaries (pkexec) or not maintained anymore (pkla-compat).
This change will thus split pkexec from the polkit package and make it a recommended only sub-package. Similarly, it will make the polkit-pkla-compat package a recommended package too. This will enable users and desktop no longer relying on those features to avoid installing them. Users that still need those features will easily be able to install them.

Upgrade/compatibility impact
Nothing happens during upgrades for existing systems as the packages are still available and will be kept as is and the new pkexec package will be added for user not deselecting recommends.
Only new installations that will not have those packages will be impacted and the risk of security issues with the pkla rules removal is low.
How To Test
Install the latest polkit, remove pkexec subpackage and pkla-compat package and ensure that your application and desktop are still working as intended.
