Add missing parameter in C API (#11542)

Summary:
The class `NewCompactOnDeletionCollectorFactory` exposes the parameter `delete_ratio`.

The C API `rocksdb_options_add_compact_on_deletion_collector_factory` does not allow a user to pass a delete ration to be passed down the the C++ class bellow.

The class has default value for the delete ratio which makes it pass the compilation and the tests.
