feat: support pattern matching in switch statements

[clementdessoude]

What changed with this PR:

Supports pattern matching in switch rules.

Still needs a few unit tests to check everything is ok.

Example

// Input
class T {
    static String formatterPatternSwitch(Object o) {
        return switch (o) {
            case

                Integer i ->


                String.format("int %d", i);
                    case Long l    -> String.format("long %d", l);
            case Double d  -> String.format("double %f", d);
            case String s  -> String.format("String %s", s);
            case TOTO  -> String.format("TOTO %s", o);
            case null -> String.format("Null !");
            case default -> String.format("Default !");
                    default        -> o.toString();
        };
    }
}

// Output
static String formatterPatternSwitch(Object o) {
    return switch (o) {
      case Integer i -> String.format("int %d", i);
      case Long l -> String.format("long %d", l);
      case Double d -> String.format("double %f", d);
      case String s -> String.format("String %s", s);
      case TOTO -> String.format("TOTO %s", o);
      case null -> String.format("Null !");
      case default -> String.format("Default !");
      default -> o.toString();
    };
  }
