The launcher version event will measure the launcher semantic version into the COS CEL. The semantic version is formatted as little-endian uint32s, with major, minor, patch ordering.
This will be useful when users want to see what bank hash algorithms are implemented.
The first COS event in the COS CEL can optionally be a launcher version. If that event does not exist, we set the MachineState.Cos.LauncherVersion to major: 0, minor: 1, patch: 0.
Test with a launcher version event, without a launcher version event,
and with a malformed launcher version event.
