Support enable_gc in disk table

**Describe the feature you'd like**

Like MemTable, also support `enable_gc` option in disk table

Look at how enable_gc is implemented in MemTable, likely in src/storage/mem_table.* or similar. Then find the disk table implementation, perhaps in src/storage/disk_table.*, and add the same option. Check for existing tests related to garbage collection in disk tables to understand the expected behavior.
