Subject: Convert command string to encoded binary in heart:set_cmd/1

OTP-10843

In order to allow unicode filenames in heart commands, the command
string is now encoded according to the file name translation mode of
the emulator (file:native_name_encoding()) before it is sent to the
heart process.
