provide a little more information before calling std::terminate

I've incorporated OpenTelemetry into my program and on certain execution paths, especially on Linux, I get terminate called without an active exception or similar kinds of messages.

If I take out my OpenTelemetry initialization/cleanup functions and leave the null Otel spans and logs in there, nothing crashes. I have exception handlers defined, but there are a few cases where a raw std::terminate is called from the library.

For example: https://github.com/open-telemetry/opentelemetry-cpp/blob/848db5722e024371f41ebdecf97f70191efd2c16/api/include/opentelemetry/nostd/span.h#L103

I have no idea if this is the bug or not, but it makes it harder. I would expect a library to log something if it's going to call terminate.
