cc @tqchen @junrushao1994 if they want a better name here.

Is it possible to make it more specific? We have a few examples above like texture2d_load/store. What about dma_mem_copy() or any hexagon-specific name?

I was thinking about something with "DMA" in the name but I realized that DMA is more of an implementation detail. I ended up referencing DMA in the comments instead. Happy to take suggestions including dma_mem_copy.

I thought about:
mem_copy_local(to emphasize the local nature of the intended usage, unlikeTVMArrayCopyFromTo@junrushao1994 mentioned which might involve RPC)mem_copy_1d(if we intend to add 2d rectangular memcpy later)
But both of them don't particularly sound better.
