graphics/drm-*-kmod, graphics/nvidia-drm-*-kmod: Update DRM drivers

Several changes were made to all LTS drm-kmod branches:
1. All branches were updated with Makefile cleanups and fixes.
2. The addition of the `DMA_BUF_IOCTL_EXPORT_SYNC_FILE` and
   `DMA_BUF_IOCTL_IMPORT_SYNC_FILE` ioctls was backported to the 6.1 and
   6.6 branches.
3. A couple fixes to amdgpu and i915 drivers were committed to the 6.12
   branch.

The corresponding `graphics/nvidia-drm-*-kmod` ports were updated to
reference the latest `graphics/drm-*-kmod` ports.

graphics/drm-61-kmod: Update to latest version

This fixes compilation with clang21 (defualt on FreeBSD 16)

Sponsored by:   Beckhoff Automation GmbH & Co. KG

x11/nvidia-driver, x11/nvidia-kmod, x11/linux-nvidia-libs,
graphics/nvidia-drm*-kmod, x11/nvidia-settings, x11/nvidia-xconfig: Update to
595.58.03

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.
(580.142)
