RFR: JDK-8288475: Initializing RandomGeneratorFactory.FactoryMapHolder fails if a SecurityManager is installed

[Johannes Kuhn]

* This adds additional permissions to the jdk.random module (`RuntimePermission "accessClassInPackage.jdk.internal.util.random"`)
* The annotations of the provider classes are now parsed early.  
  This avoids putting the parts that can trigger the parsing into an `AccessController.doPrivileged()` block.
* If a `SecurityManager` is installed, `RandomGeneratorFactory.all()` will only return `RandomGenerator`s that are loaded by a system domain loader.  
  This avoids parsing annotations of user classes from a privileged context.
