This is a port to gs201 of the original gs101 change.
Mostly this change just collects existing GPU-related settings into one
place so they can be found more easily. It also removes some vestigial
and redundant settings.
* Renderscript is deprecated and we never planned to include the RS HAL.
But it was copied in (twice) from some previous device. Remove it and
things that only the RS HAL depends on.
* The separate "*32" PRODUCT_PACKAGES entries were left over from when
prebuilts had separate prebuilts modules for 32-bit and 64-bit
variants of the package, instead of using a single multilib package.
