Support negative torque for combustion engine

[ppb2020]

Some combustion engine vehicles report a negative torque under braking conditions. This cannot be properly reflected by the current definition of engine torque as it is an unsigned integer.

This change proposes modifying the combustion engine torque definition from an unsigned integre to an integer.

Based on previous discussions this would be considered as a major change as we change signal type, i.e. intended only for 5.0, not 4.1

No sign-offs in commits, that is why the DCO check fails. I noticed however that the guidelines does not specify that well if sign off should be in PR or commit(s). (FYI: @paulboyes ) But as I remember we have said that it should be in commits.

I presume that I can add a commit with just a comment, so that the sign off is in a commit.

@ppb2020 - have you checked if you can update the PR/commit, or should I assist with a "workaround"?

I have not been able to resolve the squashing issue as I always end up with two commits. Closing the PR. Will resubmit the change.
