Autogen: Check if a file is empty before reading it
Calling `std::string::front()` on an empty string results
in an undefined behavior by the C++ standard.
In gcc8 it causes an assertion to fail.
This adds a check to `AUTOGEN` if a file to read is empty
and in case avoids the use of an empty `std::string` buffer.
Closes #17793
