Unsound usages of unsafe function `slice::from_raw_parts` about candle

Thanks for the find! I was able to reproduce your example, thanks for raising this, do you mind taking a look at the linked draft PR and providing some feedback @shinmao , admittedly I'm still fairly new to rust, and especially unsafe mechanics so I could be off on my solution

hi @tomsanbear , thanks for your response. I just saw your patch with bytemuck::cast_slice that could throw error when cast to a larger-aligned slice. Also, I saw you mentioned that webgpu project heavily relied on the usages of slice::from_raw_parts. Do you think it could cause some serious security impacts in the projects? Would you like to share the case with us? :)
