Altering default `timestamp` value for the environment in `StateTest` breaks pre-merge tests

[marioevz]

Currently the Environment property is supposed to describe the environment where the transactions are executed, and in the case of the state tests, this is Block 1.

If the test specifies an env.Timestamp or env.Difficulty in a state test, the filler should be able to come up with the appropriate genesis values such that the requested environment values are valid for block 1.

Currently it does not do that, but the tests nevertheless work because the default values are env.Difficulty=0x20000, which is the minimum difficulty value, and env.Timestamp=1000.

Also, geth cannot seem to run tests where the genesis block number is not 0.

So either we limit the block number or find a way to run the tests with higher block numbers.

I think block number > 0 could also be a problem for hive but I'm not entirely sure.

I fiexed this for basefee and randao. ( in static test filler PR)
But difficulty and timestamp still need correction.
