Combobox should be reworked

[MeonisRP]

They way Combobox is implemented now is beyond my understanding. It's built on top of cmdk package which itself adds 13kb of bloat into a project. It should be built on top of select component as it's basically the same thing, but with a searchbar. Maybe I don't get something 🤔 @shadcn

The reason I'm questioning it's implementation is because I noticed it often lags on low perf machines. I get it, most devs work on Mac (myself including). But there are office machines and low tier android phones which any experienced dev should consider. Also, it certainly has some search bugs, as mentioned in #1174 and content overflow issues.

P.S I love this library and stuff. But the performance in certain components really suffers
