MDEV-31531 Remove my_casedn_str() and my_caseup_str()

Browse Source 
Under terms of MDEV 27490 we'll add support for non-BMP identifiers
and upgrade casefolding information to Unicode version 14.0.0.
In Unicode-14.0.0 conversion to lower and upper cases can increase octet length
of the string, so conversion won't be possible in-place any more.

This patch removes virtual functions performing in-place casefolding:
  - my_charset_handler_st::casedn_str()
  - my_charset_handler_st::caseup_str()
and fixes the code to use the non-inplace functions instead:
  - my_charset_handler_st::casedn()
  - my_charset_handler_st::caseup()
