Structured Logs: Logs for crashes

### Description

The initial log buffering https://github.com/getsentry/sentry-cocoa/issues/5580 only buffers the logs in memory. So when a crash happens, the logs get lost. For some crashes, it's essential to have the logs to know what caused them.

See this [develop docs page](https://develop.sentry.dev/sdk/telemetry/telemetry-buffer/mobile-telemetry-buffer/) for an exact specification.
