unify dump accounts in test runners

[jangko]

gst, evmstate, blockchain test, and utils/debug.nim have their own flavour of dump accounts.
Except for evmstate which the format have been standardized, all others should have no problem using new format.
Then we will keep the most feature complete and use it for all test runners.

GST and block chain test already using dump accounts from debug.nim. #1510
only need to unify with evmstate.
