Add AllocationCreateStrided to support lib CPU driver

 - Able to create Allocations with arbitrary alignment requirement,
   making Incremental Intrinsic Support able to run with different
   native GPU RS runtime.
 - Make compat mode CPU driver using an additional rs_compat.spec.
 - Add a compat mode only USAGE_INCREMENTAL_SUPPORT.
 - Add AllocationCreateStrided() to take an Alignment requirement (power
   of 2). Only enbled when detect USAGE_INCREMENTAL_SUPPORT.
