implement glamsterdam-devnet-8 changes

## Overview

Implement and track the execution-layer changes for **glamsterdam-devnet-8** in Erigon.

We target the cumulative **v8.0.0** test release, based on `tests-glamsterdam-devnet@v7.2.0/1`:

- **EIP-2780** — fold the transfer-log cost into `TX_VALUE_COST`, changing the cost of contract-creation transactions with value
- **EIP-8037** — rename the "regular gas" dimension to "execution gas" and update `requires`; terminology and metadata only, with no gas-model behavior change
- **EIP-8038** — correct access-list address and storage-key costs to 2,900 so prepayment does not cost more than cold access
- **EIP-8070** — track eth/72 sparse-blobpool support and execute-only test readiness while upstream resolves whether inclusion is mandatory

EELS release tracker (v8.0.0): https://github.com/ethereum/execution-specs/issues/3167

## Sub-issues (one per tracked EIP)

- #22803 — EIP-2780: Resource-based intrinsic transaction gas
- #22804 — EIP-8037: State Creation Gas Cost Increase
- #22924 — EIP-8038: State-access gas cost update
- #22808 — EIP-8070: eth/72 - Sparse Blobpool

## Notes

- The EIP-7997 / EIP-7928 activation-block interaction was removed from the v8.0.0 tracker, so it has no devnet-8 sub-issue.
- EIP-8070 is included as a tracking sub-issue even though the upstream tracker still marks mandatory inclusion as unresolved.
- EIP-8038 tracks the requested upstream EIP and execution-spec updates; add the change PR links once they are available.
- The spec-change sub-issues list their `ethereum/EIPs` change PRs. EIP-8070 instead links its EELS and Hive test references. The single EELS release pointer for the overall work is the v8.0.0 tracker linked above.
