Allow more layouts, only align where applicable

- Added block layout controls to the Co-Authors block.
- Updated Co-Authors block CSS so the default / flow layout displays co-authors in an inline style suitable for bylines.
- Added context that is passed from Co-Authors block to its descendants so controls only relevant to the inline style can be hidden when using other layouts.
- Removed support for align from the block.json file of the image and avatar blocks, instead adding it manually in the block’s edit.js so it can be omitted when using the defaut layout. When using other layouts the align controls will be removed where not applicable by `useAvailableAlignments`.
