* Closes#3079
* Closes#3086
* Depends on #3088
* Updates the coding style guidelines (CODING.md) to reflect issues not
foreseen originally
* Changes the unicode arrow printed in the REPL to `->`. This is to make
the output consistent with how function types are written in the
standard library.

- Closes#2668
This pr migrates the old named application syntax to the new one. In
order to migrate a juvix file to the new syntax it suffices to run the
formatter.
After the next release, we should completely remove the support for the
old syntax.
## Other changes
I've improved Scope negative tests. Previously, when a negative test
failed, you could only see the title of the test and the message
"Incorrect Error", as well as the Haskell file and line where the test
is defined.
This is extremely incovenient because you have to go to the haskell test
file, go to the line where the error is defined, look at the name of the
file and then visit that file. Moreover, you need to manually run the
scoper on that file to see the error that was returned.
I've fixed that and it now shows all relevant information. Example:
I've implemented this only using the `Generic` instance for the
`ScoperError` type, so doing something similar for the rest of negative
tests should be straightforward.
This PR creates a new package that's bundled with the compiler in a
similar way to the stdlib and the package description package.
## The `package-base` Package
This package is called
[package-base](ab4376cf9e/include/package-base)
and contains the minimal set of definitions required to load a Package
file.
The
[`Juvix.Builtin`](ab4376cf9e/include/package-base/Juvix/Builtin/V1.juvix)
module contains:
```
module Juvix.Builtin.V1;
import Juvix.Builtin.V1.Nat open public;
import Juvix.Builtin.V1.Trait.Natural open public;
import Juvix.Builtin.V1.String open public;
import Juvix.Builtin.V1.Bool open public;
import Juvix.Builtin.V1.Maybe open public;
import Juvix.Builtin.V1.List open public;
import Juvix.Builtin.V1.Fixity open public;
```
`Juvix.Builtin.V1.Bool` is required to support backend primitive
integers `Juvix.Builtin.V1.Trait.Natural` is required to support numeric
literals.
## The `PackageDescription.V2` module
This PR also adds a new
[`PackageDescription.V2`](ab4376cf9e/include/package/PackageDescription/V2.juvix)
type that uses the `package-base`. This is to avoid breaking existing
Package files. The Packages files in the repo (except those that test
`PackageDescription.V1`) have also been updated.
## Updating the stdlib
The standard library will be updated to use `Juvix.Builtin.*` modules in
a subsequent PR.
