Michael Butler 1791d9bfab Fix RS HIDL server, pass data by bytes instead of by elements. 
Our current stack:
  API->API_TO_HAL_translator->HAL
          ->HAL_TO_Implementation_translator->Implementation

  For most APIs:
  - API passes objectCount.
  - HAL expects objectCount.
  - Implementation expects objectCount.

  For APIs like ScriptGroupCreate:
  - API passes byteCount. And unfortunately, these APIs are part of
    NDK, we could not make them also passing objectCount like others.
  - HAL expects objectCount.
  - Implementation expects byteCount.

  So that both API_TO_HAL_translator and
  HAL_TO_Implementation_translator should correctly convert input
  objectCount/byteCount to byteCount/objectCount.

  This CL only fixes the HAL_TO_Implementation_translator part,
  whereas aosp/356395 fixes the API_TO_HAL_translator part. Both
  parts were mistakenly using byteCount as objectCount, causing
  potential out-of-bound access.
