Part of #50891

As part of the effort to consolidate the link application experience across the editor #50891, let's use LinkControl to apply links to the core/image and core/media-text blocks as well. It may be useful to have LinkControl depict what controls render when in a media context (like these two blocks).

Tasks

• Implement LinkControl within the Image block.
• Implement LinkControl within the Media & Text block.
• Add a method for LinkControl to render media-specific actions at the foot (above "Add new page").
• Do not render "Text" input field when in media-specific context.
• Add support for "Class" input field in the link settings drawer when in media-specific context (supporting existing feature-set).
