In fcl-passrc, TPasElement.GetDeclaration does not display the length of short strings
As in title. For example, the declarations in the following program:
```pascal
unit test;
{$mode objfpc}{$H+}
interface
var
X : string[10];
type
Tx = string[5];
implementation
end.
```
are shown as follows:
```
X : string
Tx = string
```
See program in the attached archive to reproduce.
