Android benchmark on CI

[louwers]

• Update Kotlin and the Android Gradle plugin version as well, because I was running into build issues when adding kotlinx.serialization as a dependency of the test app.
• Allow benchmark to be run with instrumentation test (uses Benchmark activity from Benchmark activity Android #1850)
• Make JSON payload for benchmark results to send to the API
• I created a custom test environment so that we can run the UI tests independently from the benchmarks.
• Instead of baking the input for the benchmark at build time, it will read abenchmark-input.json with the style names, style URLs and the results API. For now the benchmarks are just built and an artifact is created.

benchmark-input.json

{
  "styleNames": ["Facebook Light", "MapTiler Basic", "Americana"],
  "styleURLs": [
    "https://xxx",
    "https://xxx",
    "https://xxx"
  ],
  "resultsAPI": "https://xxx"
}```

On a follow up PR I will actually run them and report the results back on a PR.
