Add logging to internal error

Internal error call sites are propagated through the code, and might be
triggered multiple times in the course of a request, which makes them
difficult to track the source of.

This commit changes the internalError() method to include a print of
which invocation within bmcweb triggered the error, using c++20s
std::source_location mechanism.

Note:
clang-13 still doesn't implement std::source_location, so this commit
pulls source_location.hpp from lg2 to be able to support all compilers.

Tested:
Loaded in qemu, and added an internalError() call into systems.hpp for
the /redfish/v1/Systems handler.  Observed that
[CRITICAL "error_messages.cpp":234] Internal Error
../../../../../../workspace/sources/bmcweb/redfish-core/include/../lib/systems.hpp(2820:40)
`redfish::requestRoutesSystemsCollection(App&)::<lambda(const
crow::Request&, const std::shared_ptr<bmcweb::AsyncResp>&)>`:

Got printed to the bmcweb logs.
