This adds a knob to disable VA-API support. For use-cases like AI servers, which do not need to perform video acceleration, this can be a useful tweak to reduce size of the system closure a lot, as the VA-API drivers are heavy.

After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.

This updates the ipu6 driver and firmware to a more recent version,
which seems to at least work in Chrom{e,ium}.
ipu6-drivers now relies on the in-kernel ipu6 kernel driver, so we
update our logic and metadata for it.
For the open driver, the `nvidia-uvm` module does not auto-load after
`nvidia`, which makes CUDA not work.
In this case, we need to add it to `boot.kernelModules` for it to work
again.
In my experience this is required to get Plasma 6 Wayland to work on
my GTX 1080 with the proprietary driver. Otherwise, I get errors in my
`journalctl --user` about "MESA-LOADER: failed to open simpledrm" (among
many other things) and Plasma just presents a black screen with a cursor
and nothing else.
I discovered this by searching the aforementioned error and found
[this Arch Linux forum post][0] and some further clicking around led
me to [this section on the ArchWiki][1], which is where I got the
`versionAtLeast` value from.
Tested with `nvidia-x11-555.58-6.9.7`.

- rename hardware.opengl to hardware.graphics
- remove hardware.opengl.driSupport, which does nothing
- remove hardware.opengl.setLdLibraryPath, which should never be done
- rename hardware.opengl.driSupport32Bit to hardware.graphics.enable32Bit
- lost of small docs / formatting cleanups
This library does not actually need to match the Nvidia driver version,
so we do not need to make it available impurely.
This reverts the following commits.
9b3461e7ae4e353b67f6
these changes were generated with nixq 0.0.2, by running
nixq ">> lib.mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
nixq ">> mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
nixq ">> Inherit >> mdDoc[remove]" --batchmode nixos/**.nix
two mentions of the mdDoc function remain in nixos/, both of which
are inside of comments.
Since lib.mdDoc is already defined as just id, this commit is a no-op as
far as Nix (and the built manual) is concerned.
The NVIDIA X driver uses a UNIX domain socket to pass information to
other driver components. If unable to connect to this socket, some
driver features, such as G-Sync, may not work correctly. The socket will
be bound to a file with a name unique to the X server instance created
in the directory specified by this option. Note that on Linux, an
additional abstract socket (not associated with a file) will also be
created, with this pathname socket serving as a fallback if connecting
to the abstract socket fails.
The default, which was in effect prior to this change, was `/var/run`.
The effect of not setting this option was that GDM X sessions
(and other non-root sessions) would see this warning in the log files:
```
(WW) NVIDIA: Failed to bind sideband socket to
(WW) NVIDIA: '/var/run/nvidia-xdriver-b4f69129' Permission denied
```
I don't see any security implications of turning this on universally,
since there already was an abstract socket created according to the
docs.
