RFR: 8344011: Remove usage of security manager from Class and reflective APIs [v2]

[Alan Bateman]

> Remove code required for the now defunct SecurityManager execution mode from java.lang.Class, friends, and reflection APIs. Careful review is required so I've set Reviewer to 2. I've tried to keep the changes as easy to review as possible and not go over board with cleanup.
> 
> sun.reflect.misc.ReflectUtil are been hollowed out. A future pass will remove empty methods and qualified exports once the changes in "far away" code and modules is done.
> 
> In Lookup's class description, the removal of the sentence "avoid package access checks for classes accessible to the lookup class"  and the link to the removed "Security manager interactions" section is in discussion/non-normative text, just missed in the JEP 486 update that remove the linked section.
> 
> runtime/cds/appcds/StaticArchiveWithLambda.java is updated as creating the archive no longer skips a generated class.
> 
> Testing: tier1-5
