Add `select` inputs to allow users to set the parent and position of items in the menu settings. Fixes a significant problem for screen reader users that makes updating menus extremely tedious, since the options for moving items do not explicitly set a position. This is also a significant improvement for all users manipulating large menus.
This could easily be considered an enhancement, but while it is a minor enhancement for most users, it is transformative for screen reader users in managing menus, moving that interface from nearly unusable to very manageable.

Restores the Activate button's `href` native behavior by changing the AJAX activation handler introduced in 6.5.0. It restores the pre-6.5 behavior of clicking the "Activate" button, i.e. navigates the user to the button's `href` (i.e. to the `plugins.php` UI).
Why?
Feedback was given after shipping [57545] in 6.5.0 (but was unknown during the development and testing cycles) revealed significant impacts for plugins who's users valued the onboarding / configuration experiences.
6.5.3's [58081] and [58083] added a new user action / step to the workflow. Though helpful, it did not fully resolve the impacts.
For the minor, this commit seeks to restore only the "Activate" button's `href` pre-6.5 native behavior to resolve the regression.
The next phase of the Add Plugins workflow can then continue in a major release to gain the benefits of a full major to move it from ideation through the development phases. (See #61040). The questions of redirect, how / should configuration be in the workflow, etc. can best be explored and experimented with in a major.
