Adds micro benchmarks to measure low level (1) C memory reads and writes from Dart and (2) calls from Dart into C. This CL also adds a macro benchmark to measure overall performance using BoringSSL to digest data. The shared libraries are precompiled for Linux and live in cipd packages. The benchmarks run on all hardware architectures (with the exception of Linux'es hardfp on Arm32: https://github.com/dart-lang/sdk/issues/36309).
