on unix, realpath are can failed when the path not exist

jerry_char_t *
jerry_port_path_normalize (const jerry_char_t *path_p, /**< input path */
                           jerry_size_t path_size) /**< size of the path */
{
  (void) path_size;

  return (jerry_char_t *) realpath ((char *) path_p, NULL);
} /* jerry_port_path_normalize */

Currently the implementation of jerry_port_path_normalize are called realpath directly, than
may return NULL when path_p is not NULL, but that's not expected.

I fixed it locally by using https://github.com/lygstate/cpathjoin

that is do not use operating system provided fullppath realptah,
so we only need to export a single api

/**
 * Get the current working directory
 *
 * Note:
 *      Refer to https://pubs.opengroup.org/onlinepubs/9699919799/functions/getcwd.html
 *
 * @param out_buf_p Pointer to the output buffer where the normalized path should be written.
 * @param out_buf_size Size of the output buffer.
 *
 * @return The current working directory path
 */
char *jerry_port_get_cwd (char *out_buf_p, size_t out_buf_size);

is enough,
indeed, the module handling needs path.join
and nodejs have https://nodejs.org/api/path.html#windows-vs-posix
so to properly implement we needs nodejs alike path join

@LaszloLango PR prepared, better merged as Release 3.0, as
It's update the port api

We need to wrap up things for the release, we won't be able to review and merge #5198 in time, so it'll be scheduled to the next one.
