RFR: 8344299: SM cleanup in javax.naming modules [v3]

[Aleksei Efimov]

> The proposed change cleans-up `SecurityManager`, `doPriviledged`, and `AccessController` usages from `java.naming`, `jdk.naming.rmi` and `jdk.naming.dns` modules.
> 
> One noteworthy change: The `java.naming.rmi.security.manager` JNDI environment property can be used to setup the `SecurityManager`: if the property is added to an environment map the `RegistryContext` attempts to setup the `SecurityManager`. The environment property and related method are removed in this PR. 
> 
> `tier1` - `tier3`, and other non-tiered JNDI tests showed no failures related to this change.
