[WIP] let share manager handles permission increases in sharing

[karakayasemi]

Description

This PR resolves sharing permission increase issues described in below tickets.

Previously, we were determining max permission by using $share->getNode()->getPermission(). However, actual permissions need to be taken from the user who has created the share. The node inside the share is not guaranteed to be from the perspective of the sharer. This PR determines and calculate permissions by looking sharer's nodes.

I followed same logic with this PR: #26684 . I enhanced it and completed its to-do's. Share20OcsController.php has too much logic and validations inside of its methods. In a clean approach, Share manager should take care of all sorts of validations and logics instead of controller. I moved some of the validations to manager class.
