Cleanup: renaming and consistency for kernel data

* Rename "texture" to "data array". This has not used textures for a long time,
  there are just global memory arrays now. (On old CUDA GPUs there was a cache
  for textures but not global memory, so we used to put all data in textures.)
* For CUDA and HIP, put globals in KernelParams struct like other devices.
* Drop __ prefix for data array names, no possibility for naming conflict now that
  these are in a struct.
