Adds @access private to the eight underscore-prefixed functions in src/wp-includes/secrets.php:

• _wp_secrets_get_store()
• _wp_secrets_get_key_manager()
• _wp_secrets_get_provider()
• _wp_secrets_set()
• _wp_secrets_get()
• _wp_secrets_delete()
• _wp_secrets_retire()
• _wp_secrets_list()

These are internal helpers called only by core. Marking them private makes the code reference show that they are not meant for plugins or themes.

Follow-up to r64337.
