I need to cut off all the power supplys of VL53L8 to save power. Does the firmware need to be re-downloaded every time the device is powered on?

Yes it does. There is no firmware in the part, so at boot one has to download the code to get the part running.
One might think of this as a flaw, but it works out for ST. New parts (VL53L8CH) and variants for really large customers make the download quite attractive. I don't think there were any bug fix releases, although that's another argument for the download.
One has to admit it's kind of a hassle though.
