ceph-dencoder: Add missing common types to ceph-dencoder for accurate encode-decode comparison
Currently, ceph-dencoder lacks certain common types, preventing us from accurately checking the ceph corpus for encode-decode mismatches.
This pull request aims to address this issue by adding the missing types to ceph-dencoder.

To successfully incorporate these types into ceph-dencoder, we need to introduce the necessary dump and generate_test_instances functions that was missing in some types.
These functions are essential for proper encode and decode of the added types.

This PR will enhance the functionality of ceph-dencoder by including the missing types, enabling a comprehensive analysis of encode-decode consistency.
With the addition of these types, we can ensure the robustness and correctness of the ceph corpus.

This update will significantly contribute to improving the overall reliability and accuracy of ceph-dencoder.
It allows for a more comprehensive assessment of the encode-decode behavior,
leading to enhanced data integrity and stability within the ceph ecosystem.
