tracing-ohos

Composable tracing layer which logs to logcat using the OpenHarmony NDK's OH_LOG_Print function. The provided tag will be capped at 23 bytes. Logging events resulting in messages longer than 4000 bytes will result in multiple log lines in logcat. This avoids running into logcat's truncation behaviour.

This crate is mainly based on the tracing-android crate.
