    file: add function nautilus_file_is_regular_file
    
    In commit we added a new function named nautilus_file_is_regular_file
    
    The problem is that there are function present in different files
    named "!nautilus_file_is_directory()" like inside nautilus-file.c
    near line #7798. So, if any newcomer will come and look into the files
    then it is difficult for them to analyse that there is any other
    option available for file or not.
    
    To solve this issue create a new function inside nautilus-file
    with name nautilus_file_is_a_regular_file. So, we can check
    for explicit regular file type.
