Consider `except::dump_info(std::exception_ptr)`

[kammce]

Such an API would dump information about the exception to a buffer. The kinds of information that would appear there would be:

• Exception type
• Exception stack trace (if enabled)
• std::exception::what() contents if the type is derived from std::exception

We should provide a means to tell the system about the other exception types in our system that have useful information. That way, we don't have to derive from std::exception to get additional information. This could also reduce ROM size because we won't render a string or save it into our error objects. We can just keep the data we need in our error objects then render their text when the except::dump_info is called.
