improvementsVecSeq_CUPM: Fix ::Dot, ::TDot, ::WAXPYAsync, and ::AXPBYAsync to work with non-device vectorsMat_SeqDenseCUPM: fix ::SetRandom for hipMat_SeqDenseCUPM: implement conjugate on the deviceMat_SeqDenseCUPM: Fix MatMult() (and friends) when the vector is not on the deviceThis implementation assumes that the cost of moving the matrix to thehost is more expensive that moving the vector to the device, so temporarydevice copies of the host vectors are used.VecCUPM: Avoid device synchronization in some cases of ResetArray()The documentation says that the PetscDeviceSynchronization() isonly needed if CopyToDevice_() resulted in a HtoD memcpy,which would only happen if v->offloadmask == PETSC_OFFLOAD_CPU.If we test this condition, we can avoid the synchronization.This improves the peformance of MatDenseRestoreColumnVecWrite() inperformance critical loops.CUPM: use thrust::hip::par_nosync List of files: /petsc/src/mat/impls/dense/seq/dense.h
