random: Use unified object handlers

[zeriyoshi]

Perhaps they can be handled by a common object handlers.

What are you trying to achieve with this change? Is this intended to improve performance? Memory Usage? Is this just intended as a code clean?

@TimWolla
Sorry, my apologies. It is intended to reduce memory usage, albeit slightly, and clean up the code.

Hello. I created this minor PR as a form of rehabilitation, but should we merge this into master in the future?
Since it involves ABI changes, I think we should merge it after the PHP-8.4 branch is created.

If you don't see any particular benefits, I'm thinking of closing it :)

@zeriyoshi Sorry for the delay. I was busy in wrapping things up before the feature freeze and then I was on vacation.

I don't see a value-add in this change. It provides only a very small benefit in memory usage (if at all), but adds another layer of indirection that is not present in any other extension as far as I can tell. Instead of having all the object handlers clearly stated in MINIT one needs to carefully look them up. Also any future changes to them for one engine or any newly introduced engine would possibly require splitting them again.

@TimWolla
Indeed. This is a kind of unnecessary optimization.
I'll create another PR if I find a different area that needs improvement! Thanks for reviewing!
