Customized test reporting for benchmarks

This change adds a benchmarkReport task to the accompanying plugin for
androidx.benchmark which runs provides functionality to copy benchmark
report data off from instrumented devices onto host machine after the
benchmarks are done running. The benchmarkReport task is registered in a
way which will automatically run after connectedAndroidTest.

Fixes: #130444854
Test: ./gradlew benchmark:cC && ./gradlew benchmark:benchmark-gradle-api:check
