Move NVIDIA kmods to drivers.target

[yeazelm]

Related to : bottlerocket-os/bottlerocket#4218 (comment)

Description of changes:
This change moves the NVIDIA kmod package to load before drivers.target instead of preconfigured.target. This allows us to separate the state of loading all kernel modules from the rest of configuration.

Testing done:
Built NVIDIA variants for both arches and k8s 1.33 and ECS 2. Validated that the drivers come up for all 3 versions of the driver based upon hardware and fail as expected if no NVIDIA devices are present:
