handle huge tx

[fatcat22]

This PR introduces a Huge Transaction Management System for X Layer Erigon to handle large gas-consuming transactions with configurable quotas.

1. Huge Transaction Detection - Configurable threshold to identify "huge" transactions based on gas consumption relative to block gas limit.
2. Quota Management System - Implements gas quotas to prevent huge transactions from consuming entire block capacity.
3. Dynamic Configuration - New LI flags: --txpool.huge-tx-threshold-ratio, --txpool.huge-tx-quota-ratio, --txpool.ignore-huge-tx-quota-interval

E2E Test Scenarios

Test Scenario	Threshold	Quota	Ignore Interval	Description	Expected Behavior
S1 - NoHuge_AllOrderByPrice	5%	10%	5 blocks	All transactions below huge threshold	Normal transaction ordering by gas price
S2 - HugeUnderQuota_OrderByPrice	5%	50%	50000 blocks	Mix of huge and normal txs, quota not exceeded	Transactions ordered by gas price within quota
S3 - HugeOverQuota_LimitHugeCount	5%	50%	50000 blocks	Huge transactions exceed quota limit	Quota enforcement limits huge tx inclusion
S4 - AllHuge_ExceedQuota_OrderByPrice	5%	50%	50000 blocks	All transactions are huge, exceed quota	Only quota-allowed huge txs included
S5 - AllHuge_Quota100_OrderByPrice	5%	100%	50000 blocks	All huge transactions, full quota	All huge txs included, ordered by price
S6 - Quota0_NormalFirst_ThenHuge	5%	0%	50000 blocks	Zero quota for huge transactions	Normal txs processed first, huge txs blocked
S7 - IgnoreInterval0_Mix_HugeOverQuotaAllowed	5%	50%	0 blocks	Quota ignored (interval=0)	All transactions processed regardless of quota
S8 - HugeOverQuota_NormalPartialFill	5%	25%	50000 blocks	Normal txs partially fill block	Remaining space filled with huge txs within quota
S9 - Quota100_AllNormal_OrderByPrice	5%	100%	50000 blocks	All normal transactions, full quota	Standard transaction ordering by gas price
S10 - Quota100_Mix_NormalAndHuge	5%	100%	50000 blocks	Mixed transactions, full quota	Optimal mixing of normal and huge transactions
S11 - Quota0_IgnoreInterval0_Mix	5%	0%	0 blocks	Zero quota but ignore interval=0	All transactions processed (quota bypassed)
S12 - Quota0_IgnoreInterval0_AllHuge	5%	0%	0 blocks	All huge txs, zero quota, ignore quota	All huge transactions included
S13 - Quota0_NoGasLeft_ForHuge	5%	0%	50000 blocks	No gas remaining for huge txs	Huge transactions rejected due to insufficient gas
S14 - SequentialHugeTxs_SameAddress_NaturalTxpoolBehavior	5%	50%	50000 blocks	Sequential huge transactions from same address	Multi-block distribution with efficient packing and natural txpool behavior observation
S15 - VeryHugeTx_With99Transfers_TransfersFirst	5%	50%	50000 blocks	99 normal transfers (10 Gwei) + 1 very huge tx (2.65M gas, 50 Gwei)	Transfers fill first block completely, very huge tx rejected due to exceeding block gas limit
S16 - Mix_50Transfers_10HighGas_SamePrice	5%	50%	50000 blocks	50 transfers + 10 high gas txs (same 15 Gwei) + 1 very huge tx (2.65M gas, 50 Gwei)	All transfers included, high gas txs limited by quota, efficient block filling
