Message:

Themes: Introduces block-based template parts for Classic themes.

Allows Classic / Hybrid themes to use block-based template parts without using complete block-based templates.

• Exposes the Site Editor's template parts UI
• Adds Appearance > "Template Parts" menu
• Enabled within the theme via adding a theme support for 'block-template-parts'

  add_theme_support( 'block-template-parts' );
  

This is a backport from Gutenberg.​See WordPress/gutenberg PR 42729.

Follow-up to [52330], [52069], [52178].

Props mamaduka, fabiankaegy, poena, scruffian, manfcarlo, bernhard-reiter, hellofromTonya.
See #56467.
