Revert "fix(gasmeter): account for new-account and memory gas in TRON instructions"

[yanghang8612]

Summary

Reverts the gas-metering changes introduced in #120 (commit abbdee3), restoring libevmasm/GasMeter.cpp to its prior state.

This reverts:

• The two memoryGas(...) charges added to NATIVEVOTE.
• Splitting NATIVEDELEGATERESOURCE / NATIVEUNDELEGATERESOURCE out of the shared Stake-2.0 group to add callNewAccountGas.

The six V2 opcodes are merged back into the single freezeV2Gas branch, and NATIVEVOTE is back to charging only voteGas.

Note: #120 only affected compile-time gas estimation in the optimizer, not runtime correctness — so this revert likewise has no effect on generated bytecode semantics.

Clean revert: no commit after #120 touched this file. solc builds cleanly.

Targets release_0.8.28.
