EVMC: Add missing EIP-2929 (Berlin) functions to EVMC host
The update for London (EIP-1559) in 1cdb30df ("bump nim-emvc with evmc revision
8.0.0 to 9.0.0") really bumped EVMC ABI version from 7.5 up to 9.

In other words, it skipped Berlin, going direct from Istanbul to London.

That was accompanied by EVMC changes in 05e9b891 ("EIP-3198: add baseFee op
code in nim-evm"), which added the API changes needed for London.

But the missing Berlin functions weren't added in the move to London.

As a result, our EVMC host became incompatible with Berlin, London, and really
all revisions of the ABI, and if a third party EVM was loaded, it crashed.

This commit adds the missing Berlin host support, and makes our ABI
binary-compatible with real EVMC again.

preparation for London hard fork
This preparation is needed for subsequent
EIPs included in London.

- Add London to Fork enum
- Block number to fork
- Parsing London fork in chain config
- Prepare gas costs table for London
- Prepare EVM opcode dispatcher for London
- Block rewards for London
- Prepare hive script for London

reset explicit import paths for local modules
why:
  it was convenient to have relocatable source modules when writing the
  vm interface wrappers. this patch moves it back to the standard.

also:
  there are no deep links into the vm folder anymore which leaves some
  room for manoeuvring inside

remove relative paths ./ and ../ from import section
why:
  relative paths make sources inherently non-relocatable

details:
  import base is set to the nimbus directoy, so importing ./stack
  from file interpreter.nim becomes vm/stack etc.

caveat:
   a file named nimbus/strformat.nim would clash with strformat (but
   not with std/strformat)
