Restore offset/length in QQmlJS::DiagnosticMessage

This is needed in a few places outside of declarative, so this change
restores the loc member in DiagnosticMessage and moves
QQmlJS::AST::SourceLocation into common's QQmlJS namespace/directory.
QQmlError is unaffected and retains only line/column.
