Add runsc symbolize command.
This command takes instruction pointers from stdin and converts them into their corresponding file names and line/column numbers in the runsc source code. The inputs are not interpreted as actual addresses, but as synthetic values that are exposed through /sys/kernel/debug/kcov. One can extract coverage information from kcov and translate those values into locations in the source code by running symbolize on the same runsc binary. This will allow us to generate syzkaller coverage reports. PiperOrigin-RevId: 347089624
