Summary

Update to latest Production Branch of drivers 595.58.03:
https://www.nvidia.com/en-us/drivers/details/265873/

Linux counterparts for x11/linux-nvidia-libs:
https://www.nvidia.com/en-us/drivers/details/265870/

Also bump -devel variant to match with master ports, as Production
Branch [PB] of drivers have now higher version than New Feature
Branch [NFB] of drivers.

As this update drops a bunch of old (pre-Turing generation of
architectures) GPUs as done in -devel variants updated 20260103,
add -580 variant of legacy branch of driver.

Currently, this is exactly the same version before this update.

Should I reroll the diff for UPDATING?
There are already several ports adding UPDATING entries and causing merge conflicts.
