    misra: increase identifiers length to 63 and align doc with ECLAIR config
    
    Currently the identifiers characters limit is arbitrarily set to 40. It
    causes a few violations as we have some identifiers longer than 40.
    
    Increase the limit to another rather arbitrary limit of 63. Thanks to
    this change, we remove a few violations, getting us one step closer to
    marking Rules 5.2 and 5.4 as clean.
    
    The ECLAIR configuration is already using 63, so this change matches
    the rules.rst documentation with the ECLAIR behavior.
