perf(store): improve compliant prop getter

This commit enhances the `compliantPropGetter` function's implementation. The prop getter
is heavily utilized in NGXS. I noticed that the function unnecessarily copies `paths`. It
now returns a function that accepts an object as a parameter and attempts to select a property
deeply. We've replaced the use of `reduce` with a single for-loop, making it simpler. Though
it doesn't significantly impact size, there's only a minor difference in production bundle size.

Regarding performance, I checked the `perf.link` service and got the following results:
- Old compliant prop getter: 220,410 ops/s
- New compliant prop getter: 360,480 ops/s

I generated a deeply nested object and set my CPU slowdown to 6x. The new implementation is only
30% faster, but it's reasonable to have a slightly faster implementation if possible. At least it's
not causing any negative impact.
