feat: hathorlib blueprint move 5

[r4mmer]

Motivation

To be able to implement the blueprint simulator on hathorlib there is a significant amount of code that needs to be moved from hathor/ to hathorlib/.
Since moving this amount of code can cause instabilities we are breaking down these changes into more manageable and reviewable PRs.

This is the fifth PR in this sequence.

Acceptance Criteria

Move Blueprint core, context, method parsing, and accessors to hathorlib.

Changes of note:

• hathorlib/nanocontracts/rng.py : NanoRNG changed to use plain bytes instead of Hash (from hathor/difficulty.py)
• hathorlib/nanocontracts/utils.py : Moved the utils is_nc_public_method, is_nc_view_method, is_nc_fallback_method
• hathor/nanocontracts/context.py : Context.create_from_vertex classmethod was moved to separate utility create_context_from_vertex
• hathor/nanocontracts/vertex_data.py : create_from_* classmethods were converted into standalone factory methods (e.g. create_vertex_data_from_vertex, create_block_data_from_block, etc.)
• hathor/transaction/base_transaction.py : TxVersion was unified on hathorlib so it can be used in nanocontracts dataclasses.
  • The deprecated nano contract variant will be removed.

Changes of note

• Include here all things that this PR should solve
