Support Polygon Finalized Blocks

[Lohann]

Feature description
Polygon PoS node doesn't support querying finalized blocks, instead Integrators should use L1 state root checkpoints as a measure of finality. When a state root checkpoint containing a given transaction is finalized on the L1, the Polygon transaction may be considered final. State root checkpoints occur roughly every 30 minutes.

Polygon mainnet finalized blocks can be by queried by listen to NewHeaderBlock events from this contract:
https://etherscan.io/address/0x86E4Dc95c7FBdBf52e33D563BbDB00823894C287#events

Expected output

• Query polygon finalized blocks from ethereum checkpoints
• Write unit tests
