Marko Mäkelä 228b7e4db5 MDEV-13626 Merge InnoDB test cases from MySQL 5.7
This imports and adapts a number of MySQL 5.7 test cases that are
applicable to MariaDB.

Some tests for old bug fixes are not that relevant because the code
has been refactored since then (especially starting with
MariaDB Server 10.6), and the tests would not reproduce the
original bug if the fix was reverted.

In the test innodb_fts.opt, there are many duplicate MATCH ranks, which
would make the results nondeterministic. The test was stabilized by
changing some LIMIT clauses or by adding sorted_result in those cases
where the purpose of a test was to show that no sorting took place
in the server.

In the test innodb_fts.phrase, MySQL 5.7 would generate FTS_DOC_ID that
are 1 larger than in MariaDB. In innodb_fts.index_table the difference is 2.
This is because in MariaDB, fts_get_next_doc_id() post-increments
cache->next_doc_id, while MySQL 5.7 pre-increments it.
