  Add an option to copy the artifact to vendor partition
  
  Add a --copy-to-vendor-partition optional argument to both roll_aosp.sh
  and generate_android_bp.py. When specified the root targets will be
  generated with vendor: true and a relative install path to egl folder,
  so that we can use ANGLE as the Android OpenGLES driver when the system
  starts up.
  
  Test: run roll_aosp.sh --copy-to-vendor-partion, build the Android image
  with m -j72, load the image with the Android emulator and find all ANGLE
  related *.so's are under the /vendor/lib/egl folder.
