Fix Makefile target bugs for formatting and type Checking Juvix files (#2057)
This PR resolves a few bugs in the Makefile targets for formatting and
type checking Juvix files, which were preventing the capture of type
checking errors for our examples and bad formatting for all the Juvix
files in the repository. With this PR, our code should now be clean, and
we can expect every file to be properly formatted and type checked.

Changes made:

- [x] Updated `make format-juvix-files`
- [x] Updated `make check-format-juvix-files`
- [x] Formatted all Juvix files
- [x] Comment a fragment in `examples/milestone/Bank/Bank.juvix`

In the future, we will drastically simplify the Makefile once we improve
the `format` and the `type check` command for example posted here:

- #2066 
- #2087 

Related:

- #2063 
- #2040 (due to some typechecking errors we're not capturing before)
- #2105

Fix dependencies suggestion in missing module error (#2024)
If an import statement to a missing module occurs when parsing in a
project with no dependencies the error message has the following form:

```
The module Foo does not exist.
It should be in /Users/paul/heliax/juvix-2023/tests/negative/NoDependencies/Foo.juvix
or in one of the dependencies:
```

This PR changes this error message to the `or in one of the
dependencies:` line is omitted from the error message when there are no
dependencies in the project.

This commit also adds a negative parse error test for missing module.

Add builtin integer type to the surface language (#1948)
This PR adds a builtin integer type to the surface language that is
compiled to the backend integer type.

## Inductive definition

The `Int` type is defined in the standard library as:

```
builtin int
type Int :=
  | --- ofNat n represents the integer n
    ofNat : Nat -> Int
  | --- negSuc n represents the integer -(n + 1)
    negSuc : Nat -> Int;
```

## New builtin functions defined in the standard library

```
intToString : Int -> String;
+ : Int -> Int -> Int;
neg : Int -> Int;
* : Int -> Int -> Int;
- : Int -> Int -> Int;
div : Int -> Int -> Int;
mod : Int -> Int -> Int;

== : Int -> Int -> Bool;
<= : Int -> Int -> Bool;
< : Int -> Int -> Bool;
```

Additional builtins required in the definition of the other builtins:

```
negNat : Nat -> Int;
intSubNat : Nat -> Nat -> Int;
nonNeg : Int -> Bool;
```

## REPL types of literals

In the REPL, non-negative integer literals have the inferred type `Nat`,
negative integer literals have the inferred type `Int`.

```
Stdlib.Prelude> :t 1
Nat
Stdlib.Prelude> :t -1
Int
:t let x : Int := 1 in x
Int
```

## The standard library Prelude

The definitions of `*`, `+`, `div` and `mod` are not exported from the
standard library prelude as these would conflict with the definitions
from `Stdlib.Data.Nat`.

Stdlib.Prelude
```
open import Stdlib.Data.Int hiding {+;*;div;mod} public;
```

* Closes https://github.com/anoma/juvix/issues/1679
* Closes https://github.com/anoma/juvix/issues/1984

Allow type signatures to have a body (#1785)
- Closes #1637.

A function type signature is now allowed to have a body. This is valid
for both top level and let definitions.
```

 | true := false
 | false := true
};

Throw error when reading a file that conflicts with embedded stdlib (#243)
* Throw error when reading a file that conflicts with stdlib

The Files effect first tries to read a file from the embedded stdlib. If
this succeeds and the file also exists in the project then an error is
thrown.

This error can be thrown either at the parsing stage, if the entrypoint
file conflicts with the standard library, or at the scoping stage if an
imported file conflicts.

90f607e6ce [typecheck] Shortcircuit clause pattern check errors
In the following case:

```
module WrongConstructorArity;
  inductive T {
    A : T;
  };

  f : T → T;
  f (A i) ≔ i;
end;
```

The typechecker fails when checking the clause `f (A i) := i` because of
the extra constructor argument. However if typechecking continues then
the variable `i` on the rhs does not have a type so we must short-circuit.

Restore correct handling of TypeAny and add positive typecheck tests (#34)
* [ format ] AbstractToMicroJuvix

* [ CI ] fixes

* [ CI ] fixes

* [ CI ] Using GHC 9.0 for Hlint

* [ CI ] Use static-checks for Dev as well

* [test] Add positive test for typechecker

* [test] Improve positive typechecker error output

* [typecheck] Restore correct handling of TypeAny

I mistakenly removed the matchTypes function in
https://github.com/heliaxdev/minijuvix/pull/22. This caused the handling
of TypeAny to break.

Literals have type TypeAny and so should be valid when matching against
any other type. The tests have been updated to reflect this.

* [test] Add positive MicroJuvix typecheck tests

* [ ormolu ] fixes
