1e889a6e6c MDEV-33621 Unify duplicate code in my_wildcmp_uca_impl() and my_wildcmp_unicode_impl()
This is a refactoring patch, it does not change the behaviour.
The MTR tests are being added only to cover the LIKE predicate better.
(these tests should have been added earlier under terms of MDEV 9711).
This patch does not need its own specific MTR tests.

Moving the duplicate code into a new shared file ctype-wildcmp.inl
and including it from multiple places, to define the following functions:

- my_wildcmp_uca_impl(), in ctype-uca.c

  For utf8mb3, utf8mb4, ucs2, utf16, utf32, using cs->cset->mb_wc().
  For UCA based collations.

- my_wildcmp_mb2_or_mb4_general_ci_impl(), in ctype-ucs2.c:

  For ucs2, utf16, utf32, using cs->cset->mb_wc().
  For general_ci-style collations:
      - xxx_general_ci
      - xxx_general_mysql500_ci
      - xxx_general_nopad_ci

- my_wildcmp_mb2_or_mb4_bin_impl(), in ctype-ucs2.c:

  For ucs2, utf16, utf32, using cs->cset->mb_wc().
  For _bin collations:
      - xxx_bin
      - xxx_nopad_bin

- my_wildcmp_utf8mb3_general_ci_impl(), in ctype-utf8.c

  Optimized for utf8mb3, using my_mb_wc_utf8mb3_quick().

  For general_ci-style collations:
      - utf8mb3_general_ci
      - utf8mb3_general_mysql500_ci
      - utf8mb3_general_nopad_ci

- my_wildcmp_utf8mb4_general_ci_impl(), in ctype-utf8.c

  Optimized for utf8mb4, using my_mb_wc_utf8mb4_quick().

  For general_ci-style collations:
      - utf8mb4_general_ci
      - utf8mb4_general_nopad_ci
