Accept innodb_flush_method values previously allowed on Unix only
map them to corresponding Windows CreateFile flags,
O_DSYNC=>FILE_FLAG_WRITE_THROUGH
ALL_O_DIRECT=>FILE_FLAG_NO_BUFFERING
Ability to specify innodb_flush_method=O_DSYNC fixes MySQL Bug#31876
(InnoDB commit performance slow on Windows XP), by removing an extra FlushFileBuffers()
call overhead.
