feat(logs): Add sentry.origin attribute for log handler (#4250)

resolves https://linear.app/getsentry/issue/LOGS-13

Docs:
https://develop-docs-git-abhi-logs-sdk-developer-documentation.sentry.dev/sdk/telemetry/logs/#default-attributes

> If a log is generated by an SDK integration, the SDK should also set
the sentry.origin attribute, as per the [Trace
Origin](https://develop-docs-git-abhi-logs-sdk-developer-documentation.sentry.dev/sdk/telemetry/logs/traces/trace-origin/)
documentation. It is assumed that logs without a sentry.origin attribute
are manually created by the user.
