 Reject import declaration with semicolon in GHCi

 Now GHCi rejects input containing an import declaration and semicolon,
 and prints an appropriate error message. Before, the stuff after an
 import declaration and semicolon got ignored (most of the time), without
 telling the user about it. As the default behaviour of GHCi is to reject
 multiple commands in a single input, we extend this behaviour to import
 commands.

 This patch fixes #10663.

 (See https://phabricator.haskell.org/D1518 for the introduction of
 `is_import` and `is_decl`.)
