AccessLog should use raw_path

[synodriver]

Some asgi frameworks, for example, starlette, modifies scope["path"] during execution, which confuses the log output because hypercorn uses that to record the path.

Step to reproduce

• The code

from fastapi import FastAPI

app = FastAPI(title="CGI Server")

app.mount("/cgi-bin", Someapp)  # type: ignore

if __name__ == "__main__":
    import asyncio

    from hypercorn.asyncio import serve
    from hypercorn.config import Config

    conf = Config.from_mapping(accesslog="-", bind="0.0.0.0:8000", loglevel="DEBUG")
    asyncio.run(serve(app, conf))  # type: ignore

• Then

curl http://127.0.0.1:8000/cgi-bin/env.cgi

expected

got
