Editor: Expose the Site Editor Patterns page for classic themes.

The Site Editor Patterns page was exposed internally for the Classic theme as of WP6.5. As we aim to officially expose the new Patterns page as of WP6.6, this changeset makes the following changes available when a classic themes is activated:

- Link Appearance > Patterns submenu to the Site Editor Patterns page located at `wp-admin/site-editor.php?path=/patterns
- Remove Template Parts submenu

Props wildworks, audrasjb, ironprogrammer, azaozz, youknowriad.
Fixes #61109.
