Fix out of gas error message

[grarco]

Describe your changes

Closes #4250.

Fixes the tx out of gas error message that was previously displaying sub-units of gas. To do so I've modified the gas meters to cache the gas limit protocol parameter to have it readily available at all times (and avoid redundant accesses to the storage).
