WL#4203 Reorganize and fix the data dictionary tests of

testsuite funcs_1
1. Fix the following bugs
   Bug#30440 "datadict" tests (all engines) fail: Character sets depend on configuration
      Solution: Test variants charset_collation_* adjusted to different builds
   Bug#32603 "datadict" tests (all engines) fail in "community" tree: "PROFILING" table
      Solution: Excluding "PROFILING" table from queries
   Bug#33654 "slow log" is missing a line
      Solution: Unify the content of the fields TABLES.TABLE_ROWS and
                STATISTICS.CARDINALITY within result sets
   Bug#34532 Some funcs_1 tests do not clean up at end of testing
      Solution: DROP objects/reset global server variables modified during testing
                + let tests missing implementation end before loading of tables
   Bug#31421 funcs_1: ndb__datadict fails, discrepancy between scripts and expected results
      Solution: Cut <engine>__datadict tests into smaller tests + generate new results.
   Bug#33599 INFORMATION_SCHEMA.STATISTICS got a new column INDEX_COMMENT: tests fail (2)
      Generation of new results during post merge fix
   Bug#33600 CHARACTER_OCTET_LENGTH is now CHARACTER_MAXIMUM_LENGTH * 4
      Generation of new results during post merge fix
   Bug#33631 Platform-specific replace of CHARACTER_MAXIMUM_LENGTH broken by 4-byte encoding
      Generation of new results during post merge fix
      + removal of platform-specific replace routine (no more needed)
2. Restructure the tests
   - Test not more than one INFORMATION_SCHEMA view per testscript
   - Separate tests of I_S view layout+functionality from content related to the
     all time existing databases "information_schema", "mysql" and "test"
   - Avoid storage engine related variants of tests which are not sensible to
     storage engines at all.
3. Reimplement or add some subtests + cleanup
   There is a some probability that even the reviewed changeset
   - does not fix all bugs from above   or
   - contains new bugs which show up on some platforms <> Linux or on one of
     the various build types
4. The changeset contains fixes according to
   - one code review
   - minor bugs within testing code found after code review (accepted by reviewer)
   - problems found during tests with 5.0.56 in build environment
