Subject: [PATCH] Themes: Add `wp-theme-<name>` and `wp-child-theme-<name>`
 classes to `body_class`.

This changeset introduces new classes to the body tag. The classes `wp-theme-<name>` and `wp-child-theme-<name>` (when the current theme is a child theme) are added, where `<name>` represents the sanitized name of the active theme.

Props cais, GaryJ, nacin, SergeyBiryukov, johnjamesjacoby, nirajgirixd, poena, audrasjb, rinkalpagdar.
Fixes #19736.
