Add mentions feature to objects in notes (#16373)

Issue #15755 

### Context
As shown in the issue, users should be able to @ objects and have it be
linked to their associated page.

### Changes Made
- Updated the BlockNote schema to include the newly created
MentionInlineContent that displays an object using a RecordChip
- Added the UI for the menu that appears to select the requested object
(similar to this example:
https://www.blocknotejs.org/examples/ui-components/suggestion-menus-slash-menu-component)
- Added a hook to retrieve the data for the UI
- Added the @ trigger to the block editor

### Result
