[BUGFIX] Properly set memcache/memcached in cache backend

parent::__construct() of MemcachedBackend calls
setCompression() which determines compression based
on state of $this->usePeclModule. This property needs
to be set before parent::__construct() is called.

Resolves: #99495
Releases: main, 12.4, 11.5
