/**
 * tokenize_input - Tokenize the input line into command arguments.
 * @line_buffer: Pointer to the buffer with the input command line.
 * @cmd_argv: Array of strings to store the command and arguments.
 * @argc: Pointer to the argument count variable.
 * @max: Maximum number of arguments allowed.
 *
 * Description:
 *   Tokenizes the input line using space as a delimiter. Allocates memory for
 *   each token using strdup and populates the cmd_argv array with individual
 *   tokens. Updates the argc variable with the count of arguments.
 *   Null-terminates the argument array.
 *
 * Return:
 *   No explicit return value.
 *
 * Note:
 *   The function frees the line_buffer if no command is provided.
 *
 * Example:
 *   Input: "ls -l"
 *   Output: cmd_argv = {"ls", "-l", NULL}, argc = 2
