[meta] Consolidate all table templates and add theme_hook_suggestions

Problem/Motivation

Several Drupal theme functions result in exactly the same markup structures. As we convert to twig we should take the opportunity to consolidate what can be consolidated, and add theme_hook suggestions where particular instances of these structures may need to be overridden independently.

Proposed resolution

Implement theme('table') wherever possible, and add theme_hook_suggestions for all variations, including:

• theme_table
• theme_image_style_list
• theme_image_style_effects
• theme_book_admin_table

Remaining tasks

• #1751194: Introduce hook_theme_suggestions[_HOOK]() and hook_theme_suggestions[_HOOK]_alter()
• #2035897: remove theme_image_style_list() and call theme('table__image_styles__list') instead
• #2035903: Remove theme_image_style_effects() and call theme('table__image_styles__effects') instead.
• #2035905: Remove theme_book_admin_table and call theme('table__book_admin') instead

User interface changes

None.

API changes

Removal of the following theme functions:

• theme_image_style_list
• theme_image_style_effects
• theme_book_admin_table
