Mauri de Souza Meneguzzo ff7986d670 go/printer: fix invalid output for empty decls
The current output for empty declarations such as var, const, import
results in "var", "const", "import" respectively. These are not valid
and the parser will promptly reject them as invalid syntax.

This CL updates this behavior by adding "()" to the output of empty
decls so the syntax becomes valid, e.g "var ()" instead of "var".

Fixes #63566
