[outliners] Turn nooutline into an Enum Attribute (#163665) 
This change turns the `"nooutline"` attribute into an enum attribute
called `nooutline`, and adds an auto-upgrader for bitcode to make the
same change to existing IR.

This IR attribute disables both the Machine Outliner (enabled at Oz for
some targets), and the IR Outliner (disabled by default).
