chore: improve uvicorn settings (#9900)
In this PR we disable the access log and the `ProxyHeaderMiddleware` (https://www.uvicorn.org/deployment/?h=proxyheaders#proxies-and-forwarded-headers).
Disable logging is recommended in point 3 of the General Test Requirements (https://github.com/TechEmpower/FrameworkBenchmarks/wiki/Project-Information-Framework-Tests-Overview#general-test-requirements) and has been done for other python tests like in https://github.com/TechEmpower/FrameworkBenchmarks/pull/9844/files.
The ProxyHeadersMiddleware is enabled by default (trusting localhost) and adds considerable latency. As such it should be disabled if not required by test requirements.
Enabling these flags increases performance (req/s) by 85% as seen in the numbers below
