Add Open GPU drivers from NVIDIA

[yeazelm]

What I'd like:
I would like to have the NVIDIA Open GPU kernel drivers available in Bottlerocket so that I can use EFA, this is related to #1031.

Ideally the driver would be chosen for the user depending on if the hardware supports the open driver. That way the correct driver is used automatically. The PCI device ID of the NVIDIA card can be used to determine if it supports the open kernel modules, if it does, then it would choose that driver instead of the current proprietary drivers in the NVIDIA variants.

The first step would be to compile in the driver from the .run archive in the kmod-5.15-nvidia and kmod-6.1-nvidia package in the core kit. Both sets of drivers can be included alongside each other and only the desired modules provided to modprobe on boot.

Currently, driverdog doesn't support the notion of two conflicting drivers (the proprietary and open source drivers use the same names and conflict with each other) so there needs to be a way to ensure driverdog only loads the desired driver. Ideally driverdog remains focused on linking and loading modules, and not on deciding which modules might be needed or choosing between configurations. ghostdog is already aware of PCI devices due to udev rules calling it so it would be a good place to put PCI device-specific code. driverdog also needs to solve the problem of only loading drivers if provided a configuration that doesn't call for linking. This will involve improving the structure of the configuration files since they assume each module needs linking when not all do (like the open GPU driver won't).

The PCI devices are enumerated pretty early in boot and ghostdog will be able to match those devices easily, but providing the right information later when driverdog needs it is the difficult part. Using /run or /etc could be racy because the PCI devices might enumerate before those filesystems are fully ready.

Things needed for this to work:

• Packaging the open kernel modules in the kmod-*-nvidia packages (Build open source NVIDIA kernel modules  bottlerocket-core-kit#118)
• Adding the additional flexibility to driverdog to handle only loading a module if needed (Add the ability for driverdog to copy modules bottlerocket-core-kit#119)
• Add the ability for driverdog to copy modules instead of link for those that are already linked
• Provide a way to select between the proprietary and open source driver at runtime (Automatically use Open GPU drivers when desired bottlerocket-core-kit#114)

Any alternatives you've considered:
Providing a different NVIDIA variant that only has the open drivers would work as well, but then users would have to choose the correct variant. That would be the only change and would make it more confusing to figure out which variant is the right one.

All the changes have been merged. This will be in the next minor release of the bottlerocket-core-kit.

Bottlerocket 1.24.0 was released with this functionality.
