Refactor frame helper to avoid py conversions when processing packets

[bdraco]

Since frame helper know about the APIConnection object now it can stay in native code the whole time to call the process_packet and report_fatal_error functions. Its a bit more tight coupling but frame helper is already tightly coupled to connection and its all internal anyways.

This makes processing incoming packets ~21% faster which is great for Bluetooth and log reader

The writer still does a lot of copying but thats mostly because of asyncio which is fixed in cpython 3.12

The performance of writing to sockets in asyncio has been significantly improved. asyncio now avoids unnecessary copying when writing to sockets and uses sendmsg() if the platform supports it. (Contributed by Kumar Aditya in gh-91166.)
