Adds support for multi-input kernels to Frameworks/RS.

This patch modifies Frameworks/RS in the following ways:
* Adjusted the data-layout of the C/C++ version of RsForEachStubParamStruct to
  accommodate a pointer to an array of input allocations and a pointer to an
  array of stride sizes for each of these allocatoins.
* Adds a new code path for Java code to pass multiple allocations to a RS
  kernel.
* Packs base pointers and step values for multi-input kernels into the new
  RsForEachStubParamStruct members.
