File and line number or macro layer in care/util.h?

[adayton1]

Some of the functions in care/util.h take a file and line number so if there is a GPU API error code returned, we can print out the file and line number of the calling location. Should all the functions take a file and line number? Do we want to provide a macro layer that injects the file and line number for users? Do we want to wait until c++ 20 when source_location becomes a thing (https://en.cppreference.com/w/cpp/utility/source_location)?
