Bugs fixes

This is a bug and deprecation release of panelizer. It officially supports Drupal 9.

This version requires Drupal 8.8. If you need to use 8.7 or lower, use Panelizer 4.2

Most of the changes were done in the 5.x branch and ported to 4.x, see below:

This is the first officially supported Drupal 9 version of Panels.

Note, this requires Drupal 8.8 and above. No other changes were made between 4.6 and 4.5 except removing deprecations.
