[lite] add more options for lite backend (#313)

* [cmake] support Android arm64-v8a & armeabi-v7a native c++ sdk * [cmake] fixed patchelf download on mac and android * [lite] Add threads and power_mode option support * [pybind] update runtime pybind for lite power mode * [python] Add set_lite_power_mode api to runtime * [Lite] add lite enable_fp16 option support * [lite] add more options for lite backend. * [cmake] fixed Paddle Lite typo * [runtime] format LitePowerMode enum comments * [runtime] format lite option comments
