[Feature #21109]

By always freezing when setting the global rb_rs variable, we can ensure
it is not modified and can be accessed from a ractor.

We're also making sure it's an instance of String and does not have any
instance variables.

Of course, if $/ is changed at runtime, it may cause surprising behavior
but doing so is deprecated already anyway.
