Themes: Improved caching in `wp_theme_has_theme_json()`. 

Improve logic in `wp_theme_has_theme_json()` to improve caching soo it takes into account that a theme can be switched. Before this function would overly cache if the current theme has a theme.json file. Now it use the value of `get_stylesheet()` as a key to an array. This way, if the value of stylesheet is changed, by either a filter or in a unit test, a new check to see if the file exists is run. For this reason, the workaround to check if unit tests are running by checking if  `WP_RUN_CORE_TESTS` constant exists can be removed.
