refactor chain to be map of blocks, traverse top to bottom

replace list in chain worker with map
reference blocks by hash in this map
keep head_block_hash list additionally to map in genserver state (should be a list because there could be multiple valid head blocks in the future)
to get list of blocks, traverse from latest, via prev_block_hash to the bottom
refactor block validation to have only block and chainstate as parameter. get the prev_block by hash from the chain, and the traverse the chain to get blocks for difficulty check
