Revert "aaudio: Set low-latency audio mode."

This reverts commit 1e016fd.

In order to use low latency mode, you need to set low latency callbacks. This has always been recommended and is apparently required on Android 15. SDL3 has these implemented correctly but SDL2 does not, so we should revert this for now.

Fixes #11376
