Motivation

Currently SGL implicitly uses --lora-paths to decide whether engine/server should be started with LoRA support enabled.

As we are going to support dynamic lora loading/unloading soon (#7446), the current implicit constraint is no longer reasonable as it should be perfectly legal for users to start a LoRA-enabled server without having to provide any lora paths, but instead load/unload adapters later as needed.
