Subject: IVGCVSW-2510 Ref workload implementation for Gather operator  * add
 implemenentation for GatherQueueDescriptor validate function  * add
 FirstInputTypedWorkload to allow type check on the first input tensor only  *
 add ref workload implemenentation for float and uint8  * add Gather layer
 support in Ref  * unit tests
