A minor performance improvement for `ɵɵdefineComponent` where the underlying `extractDefListOrFactory` call had a chain of `.map.filter` which meant that we were unnecessarily creating intermediate arrays just to filter out the null values. These changes switch to simple `for` loop to get around it.
