Handle gas related errors in tx execution/validation pipeline

[sug0]

The PGF VP and potentially other paths in our code ignore some host function errors (eg: with unwrap_or_default()), which could have been gas related. This results in the (unauthorized) prolonged execution of some tx.

Just to add some more context: this issue only affects native vps, as wasm codes (both txs and vps) are killed by the host on gas errors regardless of them being cooperative or not
