feat(tests): EIP-8037 spilled NEW_ACCOUNT gas consumed on caller halt

[chfast]

🗒️ Description

Cover EIP-8037's handling of a spilled NEW_ACCOUNT state-gas charge when the calling frame fails, a gap with no prior hand-written fixture.

• consumed_on_caller_halt: a value CALL charges NEW_ACCOUNT in the caller frame (spilling into gas_left with an empty reservoir), then the caller hits INVALID. Parametrized over in-cap/over-cap reservoir and two child outcomes: a new account (CALL succeeds) and a gas-starved precompile (CALL fails, exercising the child-failure refund path). gas_used equals gas_limit (in-cap) or the EIP-7825 cap (over-cap).
• returned_on_caller_revert: same setup ending in REVERT; the charge is refilled LIFO and refunded, so gas_used is the regular-execution cost, the same in-cap and over-cap.

Also correct the module docstring: on an exceptional halt the spilled portion stays consumed as regular gas (only the reservoir-funded portion is restored to the reservoir).

Approving!

Rebased on forks/amsterdam.

The "over-cap" parts are already covered by test_top_level_failure_spilled_state_gas & est_top_level_halt_burns_spilled_state_gas, but the "in-cap" full spill cases and the value CALL`NEW_ACCOUNT`` charge source are def new!
