1. Adds the command `just format check`, which checks that all Haskell
files are formatted.
2. In CI, we use install ormolu from stackage and run it. This will
facilitate consistency between CI and local setups.

* Closes#2781
* This PR only implements the Rust runtime. The Rust backend / code
generation need to be implemented in a separate PR.
* The tests are unit tests for different modules and tests with
"manually" compiled Juvix programs.
* Adds building & testing of the Rust runtime to the CI.
`just install` now builds the optimized binary by default.
use `just disableOptimized=yes install` to build the non-optimized
binary (with faster build time).
The numParallelJobs option on the `justfile` is used to control the
total amount of concurrency when running build commands. This PR adds
this number to the test runner command: `+RTS -N$numParallelJobs -RTS`.
This means that `$numParallelJobs` threads will be used by the test
runner.
NB: ``+RTS -N -RTS` means that tests will use the number of threads
equal to the number of CPUs on the machine.
This PR changes the CI build to use the justfile instead of the Makefile
to run builds and tests. CI builds now take advantage of parallel module
builds from https://github.com/anoma/juvix/pull/2729.
In order support this the runtime build target in the justfile now
supports `runtimeCcArg` and `runtimeLibtoolArg` so that the `CC` and
`LIBTOOL` Makefile argument can be set. This is required for the macOS
build.
In addition this PR upgrades the stack setup step action. Previously the
stack build flags included `--fast` which meant the whole project was
rebuilt in the `test` step, this has also been fixed.
Overall this speeds up the CI:
* Linux now takes 30mins (from 40mins)
* macOS now takes 60mins (from 80mins)
Thanks to @janmasrovira for figuring out that the stack
`--ghc-options=-j` flag enables [parallel module compilation in
GHC](https://downloads.haskell.org/ghc/latest/docs/users_guide/using.html#using-ghc-make).
This PR adds support for this in the project justfile.
You can configure the argument to `-j` using the `numParallelJobs`
option, for example:
```
just numParallelJobs=24 build
+ stack build --fast -j24 --ghc-options=-j24
```
If `numParallelJobs` is not set then `-j` is passed with no arguments in
`--ghc-options` (this is equivalent to passing the number of cpus of the
machine.) and is passed with the number of cpus of the machine for the
stack `-j` option (the stack `-j` option requires an argument).
The `numParallelJobs` option also sets the argument to the [stack `-j`
option](https://docs.haskellstack.org/en/stable/global_flags/#-jobs-or-j-option).
To disable build parallelism set the `disableParallel` flag:
```
just disableParallel=yes build
+ stack build --fast
```
