[vala/staging] Add boolean CodeContext.keep_going and corresponding compiler option

[Rico Tzschichholz <ricotz src gnome org>]

commit 1430c461d4a45026331663989113feb195588255
Author: Rico Tzschichholz <ricotz ubuntu com>
Date:   Mon Sep 2 15:25:44 2019 +0200

    Add boolean CodeContext.keep_going and corresponding compiler option
    
    If keep_going is set then check() will continue after hitting errors in
    resolver and analyzer.
