explicit cancel collation flow

[SmaGMan]

Use explicit flow to cancel active collations on the block mismatch or when received a block from bc far ahead of last collated. Now we drain active collation tasks in a separate cancel task and do not relay on collator result cancellation using flags. Removed races when shard collator trying to collate next block even if cancellation requested before sync.

Collation manager code was splitted on several modules.

Notes/Additional Comments:

Better to review all commits except the last one separately because the last commit only moves working code from a single file to a several modules.
