feat(tests): EIP-7934 - block rlp size limit test cases

[spencer-tb]

🗒️ Description

Creates the initial set of test cases for EIP-7934 and the new exception type BlockException.RLP_BLOCK_LIMIT_EXCEEDED.

Currently there are only 2 simple tests cases:

• test_block_exceeds_rlp_size_limit, this send a single tx that "should" exceed the block rlp size.
• test_multiple_transactions_exceed_limit, this sends 5 txs where the last should push the block rlp over the limit.

Note that currently assume that 10_000 extra calldata bytes of a tx will exceed the limit of 8_388_608 RLP encoded bytes. Note we use the precise limit:

MAX_BLOCK_SIZE - SAFETY_MARGIN = MAX_RLP_BLOCK_SIZE
10_485_760 (10 MiB) - 2_097_152 (2MiB) = 8_388_608

Client specific exceptions will need to be added in a follow up PR, or in this PR one they are ready.

Insane precision:

LGTM, the precision is amazing.

I pushed a tiny change that renames a couple of variables and test IDs.

Also created an issue to follow up on cases I think are missing: #1772

LGTM!
