Add validation support for ImageGatherBiasLodAMD (#3363) 
ImageGatherBiasLodAMD makes it possible to use the Bias and Lod image
operands with OpImageGather and OpImageSparseGather. This commit makes
sure the validator checks for that capability before reporting errors
and adds a few positive tests.
