Use `Base.strict_decode64` instead of `Base.decode64` just as we do in encoding;

Also reduce extra object allocation by creating string directly instead of join on Array

better error message for constants autoloaded from anonymous modules [fixes #13204]

load_missing_constant is a private method that basically plays the role of const_missing.
This method has an error condition that is surprising: it raises if the class or module
already has the missing constant. How is it possible that if the class of module has
the constant Ruby has called const_missing in the first place?

The answer is that the from_mod argument is self except for anonymous modules, because
const_missing passes down Object in such case (see the comment in the source code of the
patch for the rationale).

But then, it is better to pass down Object *if Object is also missing the constant* and
otherwise err with an informative message right away.
