 Fix &raw_output and enable_raw_output interpretation of NUL characters

 When using a `print` statement to write to a file that has raw output
 enabled, NUL characters in string are no longer interpreted into "\0",
 no newline is appended afterwards, and each argument to `print` is
 written to the file without any additional separation.

 (Re)Assigning to identifiers with the &raw_output attribute should also
 now correctly apply the attribute to the file value being assigned.

 Note that the write_file BiF should already be capable of raw string
 data to a file, expect it bypasses the print_hook event.
