There are a variety of operations a WordPress user can only perform if they have the correct capabilities. A REST API client should only display UI for one of these operations if the WordPress user can perform the operation.
Rather than requiring REST API clients to calculate whether to display UI based on potentially complicated combinations of user capabilities, `targetSchema` allows us to expose a single flag to show whether the corresponding UI should be displayed.
This change also includes flags on post objects for the following actions:
- `action-publish`: The current user can publish this post.
- `action-sticky`: The current user can make this post sticky, and the post type supports sticking.
- `action-assign-author': The current user can change the author on this post.
- `action-assign-{$taxonomy}`: The current user can assign terms from the "$taxonomy" taxonomy to this post.
- `action-create-{$taxonomy}`: The current user can create terms int the "$taxonomy" taxonomy.
