Move InlineBlockEditing to CMS UI

Description

Inline block editing features have been moved from the Episerver Block Enhancements Labs add-on to CMS UI.

This feature allows editors to edit block content in a "quick edit view" without changing the current content context. A dialog box with an editable form is opened by selecting Quick Edit from the block's content menu.

In the inline edit dialog box, editors can also publish the block, mark the block as Ready to Publish, or send the block to review depending on the context and user's access rights.

See Linh Nguyen's blog post and the developer guide topic Inline edit blocks for more information.
