RFR: 8344397: Remove Security Manager dependencies from java.security and sun.security packages [v4]

[Sean Mullan]

> Now that JEP 486 has been integrated, `java.security` and `sun.security` implementation dependencies on `System.getSecurityManager` and `AccessController.doPrivileged` can be removed. 
> 
> This should cover most of the remaining cleanup in the security libraries area. A couple of the `sun.security.action` classes can't be removed yet, as well as a few constants in `sun.security.util.SecurityConstants` and internal `ProtectionDomain` methods until dependencies are removed in other areas. Some additional test cleanup can also be done later.

Sean Mullan has updated the pull request with a new target base due to a merge or a rebase. The pull request now contains 10 commits:
