Block consensus validation when it process a block for transaction decoupling #4

[Bigpiggy01]

Block consensus validation when it processes a block:

Construct a raw block equivalent with existing block structure by pulling raw tx from buspool
then reconstruct raw block then get pass through block validation logics.

1. Chainlocked tx would only do basic check
2. Output amount > input amount
3. No negative output
4. No spent input
5. Block get stored in blockdb with the reconstruct raw block (i,e include raw tx from both mempool and buspool)
