MDEV-32242 innodb.doublewrite test case always gets skipped
- Split the doublewrite test into two test (doublewrite,
doublewrite_debug) to reduce the execution time of the test
- Removed big_test tag for the newly added test case
- Made doublewrite test as non-debug test
- Added search pattern to make sure that InnoDB uses doublewrite buffer
- Replaced all kill_mysqld.inc with shutdown_mysqld.inc and
zero shutdown timeout
- Removed the case where fsp_flags got corrupted. Because from commit
3da5d047b8 (MDEV-31851) onwards,
doublewrite buffer removes the conversion the fsp flags from buggy
10.1 format
Thanks to Marko Mäkelä for providing the non-debug test
