Misc Vec Fixes

Closes #1184

See merge request !5677

Prior to this change, the user was responsible for ensuring that the
coordinate order matches the solution order because CGNS needs them to
be collocated. Now we do the projection automatically when necessary.

If!defined() -> ifndef

Change the remaining if !defined() header guards that were missed during The Great Formatting 2 to ifndef

The percentage of time etc in the stage will thus be useful in understanding the performance of the entire solver inside the PCMPI
