Explode preserved cycles

Context

based on !11300 (merged)

This MR divide finish the division of preserved_cycles constant in several constants with different purpose.

The idea is that preserved cycle is used for different purposes sometimes with narrow link between all its usages.

We retained 3 different usage :

• consensus_rights_delay
• delegate_parameters_activation_delay
• block_conservation_cycles blocks_preservation_cycles (for the shell)

As you can see in constants_storage diff, we added other constants as pseudo-paramaters :

• issuance_modification_delay
• adaptive_issuance_activation_delay
• slashable_deposits_period
• tolerated_inactivity_period
• consensus_key_activation_delay

The MR is currently being split into smaller parts to make it more readable: see

• !11558 (merged) preliminary cleanup
• !11562 (merged) for everything related to delegate_parameters_activation_delay (with extra tests)

and more to come ...

• pseudo constants !11627 (merged)
• consensus_right_delays everywhere else and remove preserved_cycle + update doc !11629 (merged)
