v3.1: svm: properly test underfunded nonce fee-payer (backport of #9246)

[mergify]

Problem

the "Insufficient Fees" branch of test_validate_transaction_fee_payer_is_nonce() does not actually set up a NonceInfo on CheckedTransactionDetails, so the nonce account is tested as an ordinary fee-payer

this isnt really a gap in test coverage now since the two validation steps are functionally independent, but the interrelationship is crucial for simd290/simd297

Summary of Changes

create a valid nonce nonce account and NonceInfo so we properly go through this code path
