(reland 3) Upgrade sensors to @2.0

Notices:
* a.h.sensors@2.0-impl.ranchu is installed into
  /vendor/lib(64)? instead of /vendor/lib(64)?/hw
  because a.h.sensors@2.0-service.multihal does not
  look for libraries in the hw directories unless
  full path is provided and it is bitness-dependent,
  see b/154634207.

* hals.conf is placed into the etc directory using
  PRODUCT_COPY_FILES instead of prebuilt_etc due
  to technical debt in our build files around wifi
  HAL libraris. aosp/1293093 has to be landed
  properly to resolve this, see aosp/1293576.
