  Log Message:
  -----------
  [OpenMP] cmake option LIBOMPTARGET_NVPTX_MAX_SM for nvptx device RTL

It allows customizing MAX_SM for non-flagship GPU and reduces graphic memory usage.

In addition, so far the size is hard-coded up to __CUDA_ARCH__ 700 and is already a hassle for 800.
Introduce MAX_SM for 800 and protect future arch
