Subject: [PATCH] Boostrap: Move `is_ssl()` to wp-includes/load.php.

Moving to load.php introduces parity with other commonly evaluated `is_*()` functions such as `is_admin()` or `is_multisite()`.  It also makes `is_ssl()` available much earlier in the loading process, such as for use in drop-ins like advanced-cache.php.

Props johnjamesjacoby.
Fixes #35844.
