Allow tcc arguments to be read from @listfiles

    Subject: Allow tcc arguments to be read from @listfiles

    This allows all @ prefixed arguments to be treated as listfiles
    containing list of source files or tcc options where each one is on a
    separate line. Can be used to benchmark compilation speed with
    non-trivial amount of source files.

    The impl of `tcc_parse_args` had to be moved to a new function that is
    able to be called recursively w/ the original one remaining as a driver
    of the new one. Listfiles parsing happens in a new
    `args_parser_add_listfile` function that uses `tcc_open`/`tcc_close/inp`
    for buffered file input.
