Directives should be allowed inline

[timotheeguerin]

Right now suppress needs to be on its own line, it would be nice to be able to target every nodes in the syntax tree. Otherwise we are unable to suppress everything

model Foo {

  name: string;


  nested: #suppress("no-nullable" "We do actually need no nullable for this nested props") {
    prop1: string | null;
    prop2: string | null;
  }
}
