Implement block synchronization mechanism introduced in the Introduce BFT consensus protocol LIP.

[SargeKhan]

Expected behavior

Introduce BFT consensus protocol LIP introduces new specifications for a node to synchronize to the tip of the blockchain in the network. Therefore, the current syncing mechanism should be replaced with the new specification.

Child issues:

• [x] Implement Blocks Synchronizer class to combine Block Synchronization Mechanism logic #3773
• [x] Implement peer selection algorithm step for Block Sync Mechanism #3767
• [x] Implement obtain tip of chain step for Block Sync Mechanism #3768
• [x] Implement reverting to last common block step for Block Sync Mechanism #3770
• [x] Implement request and apply blocks of new chain step for Block Sync Mechanism #3771
• [x] Update Application State interface to include heightPrevoted #3774

Actual behavior

The new specification for block synchronization is not implemented in framework.

Which version(s) does this affect? (Environment, OS, etc...)

3.0.0

This is a complicated task which should be tackled in smaller issues. Therefore, the description of this issue should be updated to include a checklist of subtasks necessary to close this issue.
