Support Android target in kotlinx-benchmark

This GSoC 2024 Kotlin project proposal aims to enable kotlinx-benchmark support for the Android platform. The project will enhance the kotlinx-benchmark library to detect and adapt to the Android runtime environment, enable existing kotlinx.benchmark functionality to run on the android platform, and allow customisation of benchmark configurations via annotations or in build.gradle. The main deliverables include an updated version of the kotlinx-benchmark library for Android, sample code, updated README documentation, and tutorials for using it on the android platform.
