Integrated libocpp patch

[louisg1337]

Describe your changes

This PR integrates the libocpp.patch file that is currently being using in the charin-e2e-demo. The goal is to completely get rid of all of the patches so that the charin-e2e-demo can be fully functional and not rely on hacky patches.

Testing Done

This code was tested alongside all of the other patches in everest-demo/charin-e2e-demo. In the demo, setChargingProfile, which this patch helps implement, seems to work on a basic level.

@louisg1337 we should clean up this patch a bit before having others review it. Concretely, we should:

• downgrade all the EVLOG_errors to EVLOG_warning or EVLOG_info or...
• remove out unnecessary commented out code
• make the MessageType::SetChargingProfile handling be similar to the others

A lot of this was hacking the code together to figure out what was going on, we should clean it up before submission

@drmrd @couryrr-afs @wjmp please let us know if AFS is able to and wants to review this. Otherwise, we will just merge!

This looks fine to me for the demo code.

[shankari]

Note that we are requesting to merge this into the main libocpp, not into the demo code.
We currently have this only in the demo code through patches, but that is not a viable long-term solution.
Also the code to handle the incoming SetChargingProfile method is required to hook up the CSMS to the station, so it is most assuredly not demo code. Or are you saying that it will be reimplemented by AFS later?

I am going to merge this in the next few days

@shankari we are actively working on this implementation with test coverage.

[shankari]

ok I will merge this change, we can submit to the main everest repo once the tests are done!

@louisg1337 can you please change this to point to the charin-e2e-demo-with-revisions branch? That is the one that is used in the demo
