Plugin Directory Admin: Quick Edit should not allow slug changes on approved or rejected plugins

[Ipstenu]

Right now I can edit the slug of a live plugin is QuickEdit

This is bad.

We should remove quick editing of the slug entirely.

Replying to Ipstenu:

Seems to contradict comment:8:ticket:2249 :) Maybe limit it to new and pending plugins?

Maybe limit it to new and pending plugins?

yes :) That.

In 7791:

Plugin Directory: Limit slug changes via Quick Edit to new and pending plugins.

Also adjust the capability check for consistency with the one on Edit screen.

Props Ipstenu.
Fixes #3303.

In 7798:

Plugins: Don't dequeue inline-edit-post.js in Plugin_Posts::handle_row_actions(), as Quick Edit might be needed for new and pending plugins.

Do that in Customizations::enqueue_assets() instead.

See #3303.
