[common_test] Update common test modules to handle unicode

* Use UTF-8 encoding for all HTML files, except the HTML version of
  the test suite generated with erl2html2:convert, which will have the
  same encoding as the original test suite (.erl) file.

* Encode link targets in HTML files with
  test_server_ctrl:uri_encode/1.

* Use unicode modifier 't' with ~s when appropriate.

* Use unicode:characters_to_list and unicode:characters_to_binary for
  conversion between binaries and strings instead of binary_to_list
  and list_to_binary.
