RUM-1823: Add buildId to the RUM error and Log events

[0xnm]

What does this PR do?

This PR adds buildId support for RUM error events and Log events.

buildId will be generated by the Datadog Gradle Plugin (see DataDog/dd-sdk-android-gradle-plugin#211) only for builds which are minified.

Once attached to RUM error events and Logs events, it will be used for the symbolication.

NB: although build_id is declared in the common schema for RUM events, this PR adds it only for error events.

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
