Format all Nix files using the officially approved formatter,
making the CI check introduced in the previous commit succeed:
nix-build ci -A fmt.check
This is the next step of the of the [implementation](https://github.com/NixOS/nixfmt/issues/153)
of the accepted [RFC 166](https://github.com/NixOS/rfcs/pull/166).
This commit will lead to merge conflicts for a number of PRs,
up to an estimated ~1100 (~33%) among the PRs with activity in the past 2
months, but that should be lower than what it would be without the previous
[partial treewide format](https://github.com/NixOS/nixpkgs/pull/322537).
Merge conflicts caused by this commit can now automatically be resolved while rebasing using the
[auto-rebase script](8616af08d9/maintainers/scripts/auto-rebase).
If you run into any problems regarding any of this, please reach out to the
[formatting team](https://nixos.org/community/teams/formatting/) by
pinging @NixOS/nix-formatting.
starting with 25.0.0, mesa no longer builds CLC executables when cross compiling:
it finds the `mesa-clc` & others we explicitly provide it, decides
there's no reason to build new versions of those components, and
so cross-compiled mesa no longer produces any `cross_tools` output.
excerpted from upstream src/compiler/clc/meson.build:
```meson
if get_option('mesa-clc') != 'system' and (with_gallium_asahi or \
with_asahi_vk or \
with_intel_vk or \
with_gallium_iris or \
get_option('install-mesa-clc'))
prog_mesa_clc = executable(
'mesa_clc',
['mesa_clc.c'],
include_directories : [inc_include, inc_src],
c_args : [pre_args, no_override_init_args],
link_args : [ld_args_build_id],
dependencies : [idep_mesaclc, dep_llvm, dep_spirv_tools, idep_getopt],
# If we can run host binaries directly, just build mesa_clc for the host.
# Most commonly this happens when doing a cross compile from an x86_64 build
# machine to an x86 host
native : not meson.can_run_host_binaries(),
install : get_option('install-mesa-clc'),
)
endif
```
- add sanity check for mesa-gl-headers
- drop osmesa, gallium-nine, xatracker from default build
- move teflon to $drivers
- rename $driversdev to $cross_tools to reflect its real use
this follows the same pattern as used for mesa's `intel-clc` build helper:
1. build `mesa-clc` for the build machine.
2. provide the native `mesa-clc` when cross-compiling mesa.
the meson changes for this have been upstreamed into the next release:

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.

`virtio` is used with a virtio-gpu device supporting drm native context.
I don't know the use-cases for `wsl` and `kgsl`, but let's just enable
them too.
In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.
