gpu: nvgpu: igpu and dgpu driver libs

Different build flags are used for iGPU and dGPU in safety build. In order to support dGPU in unit tests, a separate library is needed for the driver. Added makefiles to build: - libnvgpu-drv-igpu.so - libnvgpu-drv-dpgu.so Updated scripts and units makefiles to use libnvgpu-drv-igu by default.
