feat(fixtures): Add state field to post in state tests

[marioevz]

🗒️ Description

Adds a state field to each network post result that contains the resulting allocation of the transaction execution.

This is meant to be a debugging aid in case there is a state root mismatch when consuming the tests.

Why postDecoded. There was a field postState already. We just removed it because there were too many tx and tests. So the idea was if you have a mismatch, you run test fill command with a flag that exports the post state.

But if we don't care about the size, we just restore the postState field.

it was called decoded in blockchain tests because header and data decoded from given rlp.
other than that we call it just postState

[winsvega]

lets keep original namepostState or 'state' since it is already in post dictionary

@winsvega applied the suggestion and the field is now named state.

@jochem-brouwer just a heads-up that the field was renamed.
