RFR: 8344365: SecurityManager cleanups in java.sql and java.sql.rowset modules [v3]

[Eirik Bjørsnøs]

> Please review this PR which cleans up SecurityManager-related code in `java.sql` and `java.sql.rowset` modules post JEP-486
> 
> There are quite a few changes to review, but all relatively straightforward:
> 
> `DriverManager`
> * Remove `SecurityManager::checkPermission` calls in the `setLogWriter`, `setLogStream` and `deregisterDriver` methods
> * Remove two now-unused package private SQLPermission constants
> * `ensureDriversInitialized` is updated to remove `AccessController::doPrivileged` when reading a system property and when initializing drivers
> 
> `CachedRowSetImpl`
> *  Remove `AccessController::doPrivileged` when getting a `SyncFactory` instance
> * `getObject` is update to remove a call to `ReflectUtil::checkPackageAccess`
> 
> `CachedRowSetWriter`
> * A call to `ReflectUtil::checkPackageAccess` is removed.
> 
> `SerialJavaObject`
> *  `getFields` is updated to remove call to `ReflectUtil::checkPackageAccess`. `@CallerSensitive` is no longer needed for this method.
> * The test `CheckCSMs.java` is updated to remove references to `SerialJavaObject:getFields`
> 
> `SyncFactory`
> * `initMapIfNecessary` is updated to remove call to `AccessController::doPrivileged` when reading system properties and when reading properties from an input stream
> * `getInstance` is updated to remove calls to `ReflectUtil::checkPackageAccess`
> * `setLogger` method is updated to remove call to `SecurityManager::checkPermission`
> * `setJNDIContext` methods are updated to remove call to `SecurityManager::checkPermission`
> 
> `RowsetProvider`
> *  Static initializer is updated to call `System::getProperty` directly
> * `newFactory` is updated to call `System::getProperty` directly
> * `newFactory` is updated to not call `ReflectUtil.checkPackageAccess`
> * `getContextClassLoader` is updated to not call `AccessController::doPrivileged`
> * `getFactoryClass` is updated to not call `ReflectUtil.checkPackageAccess`
> * `getSystemProperty` is removed
> 
> 
> `SQLInputImpl`
> *  A call to `ReflectUtil::checkPackageAccess` is removed
> 
>  `TestPolicy.java` in `test/java/sql/testng/util`
> * This  is now unused and removed
> 
> Ran `test/jdk/java/sql` and `test/jdk/javax/sql` tests locally. GHA results pending.
