Add Android/Robolectric visibility to Test Optimization spans

[daniel-mohedano]

What Does This Do

• Implements additional visibility to test spans for test emulated with the Android SDK through Robolectric. These tests are already traced OOTB as JUnit4 tests.
  • New per-test span tags:
    • test.android.api_level
    • test.android.release
    • test.android.codename
    • test.android.robolectric.version
  • New is_android_emulated boolean field on the test_event_finished telemetry metric.
• Adds a new GradleDaemonSmokeTest test to validate the new instrumentation and tagging. It covers both @RunWith(RobolectricTestRunner.class) and @RunWith(AndroidJUnit4.class).

Motivation

With Android tests already being supported OOTB, these changes provide better visibility for customers using the Robolectric framework.

Contributor Checklist

• Format the title according to the contribution guidelines
• Assign the type: and (comp: or inst:) labels in addition to any other useful labels
• Avoid using close, fix, or any linking keywords when referencing an issue
  Use solves instead, and assign the PR milestone to the issue
• Update the CODEOWNERS file on source file addition, migration, or deletion
• Update public documentation with any new configuration flags or behaviors
• Add your completed PR to the merge queue by commenting /merge. You can also:
  • Customize the commit message associated with the merge with /merge --commit-message "..."
  • Remove your PR from the merge queue with /merge -c
  • Skip all merge queue checks with /merge -f --reason "reason"; please use this judiciously, as some checks do not run at the PR-level (note: the PR still needs to be mergeable, this will only skip the pre-merge build)
