Added lpm4 lookupx4 implementation by using Arm SVE extension. The SVE is Scalable Vector Extension which is exposed to the user with a vector length agnostic interface. Refer to [1] for more information about SVE.
Configuration was added for Neoverse N2 CPU which has SVE support. Some bugs were fixed so compiling with sve enabled can pass.

Fixed compiling when sve was enabled.
