Mike Kolupaev fe09a6dae3 [wal changes 2/3] write with sync=true syncs previous unsynced wals to prevent illegal data loss
Summary:
I'll just copy internal task summary here:

"
This sequence will cause data loss in the middle after an sync write:

non-sync write key 1
flush triggered, not yet scheduled
sync write key 2
system crash

After rebooting, users might see key 2 but not key 1, which violates the API of sync write.

This can be reproduced using unit test FaultInjectionTest::DISABLED_WriteOptionSyncTest.

One way to fix it is for a sync write, if there is outstanding unsynced log files, we need to syc them too.
"

This diff should be considered together with the next diff D40905; in isolation this fix probably could be a little simpler.

Test Plan: `make check`; added a test for that (DBTest.SyncingPreviousLogs) before noticing FaultInjectionTest.WriteOptionSyncTest (keeping both since mine asserts a bit more); both tests fail without this diff; for D40905 stacked on top of this diff, ran tests with ASAN, TSAN and valgrind
