### What this PR does / why we need it? This PR adds sleep mode feature for vllm-ascend, when sleeps, we do mainly two things: - offload model weights - discard kv cache RLHF tools(such as https://github.com/volcengine/verl and https://github.com/OpenRLHF/OpenRLHF) have a strong need of sleep mode to accelerate the training process. This PR may solve #375 and #320 . ### Does this PR introduce _any_ user-facing change? No existing user interfaces changed. Users will have two new methods(`sleep()` and `wake_up()`) to use. ### How was this patch tested? This PR is tested with Qwen/Qwen2.5-0.5B-Instruct. At first, we have free NPU memory M1. After `llm = LLM("Qwen/Qwen2.5-0.5B-Instruct", enable_sleep_mode=True)` executed, we have free NPU memory M2. M2 < M1. Then we call `llm.sleep(level=1)`, we have free NPU memory M3. We have M3 > M2, M3 is very close to M1. Plus, we have the same output tokens before sleep and after wake up, with the config of `SamplingParams(temperature=0, max_tokens=10)` and with the same input tokens of course. This PR is utilizing the CMake procedure of #371 , thanks a lot. Signed-off-by: Shuqiao Li <celestialli@outlook.com>
