Add ObjectRegistry to ConfigOptions (#8166)

Summary:
This change enables a couple of things:
- Different ConfigOptions can have different registry/factory associated with it, thereby allowing things like a "Test" ConfigOptions versus a "Production"
- The ObjectRegistry is created fewer times and can be re-used

The ConfigOptions can also be initialized/constructed from a DBOptions, in which case it will grab some of its settings (Env, Logger) from the DBOptions.

* Removed unused structure `CompactionFilterContext`.
* The `skip_filters` parameter to SstFileWriter is now considered deprecated. Use `BlockBasedTableOptions::filter_policy` to control generation of filters.
* ClockCache is known to have bugs that could lead to crash or corruption, so should not be used until fixed. Use NewLRUCache instead.
* Added the ObjectRegistry to the ConfigOptions class. This registry instance will be used to find any customizable loadable objects during initialization.
* Expanded the ObjectRegistry functionality to allow nested ObjectRegistry instances. Added methods to register a set of functions with the registry/library as a group.
* Deprecated backupable_db.h and BackupableDBOptions in favor of new versions with appropriate names: backup_engine.h and BackupEngineOptions. Old API compatibility is preserved.
