MDEV-16596 : Windows - redo log does not work on native 4K sector disks.
Disks with native 4K sectors need 4K alignment and size for unbuffered IO
(i.e for files opened with FILE_FLAG_NO_BUFFERING)
Innodb opens redo log with FILE_FLAG_NO_BUFFERING, however it always does
512byte IOs. Thus, the IO on 4K native sectors will fail, rendering
Innodb non-functional.
The fix is to check whether OS_FILE_LOG_BLOCK_SIZE is multiple of logical
sector size, and if it is not, reopen the redo log without
FILE_FLAG_NO_BUFFERING flag.
