tsdb: add auto-cleanup to newTestHead and remove redundant cleanup calls (#17890) 
Add automatic cleanup to newTestHeadWithOptions so that heads created
with newTestHead are automatically closed when the test ends. This
simplifies test code by removing the need for manual cleanup in most
cases.

Changes:
- Add t.Cleanup in newTestHeadWithOptions immediately after creating
  the head, using _ = h.Close() to handle double-close gracefully
- Remove redundant t.Cleanup, defer, and explicit Close calls from
  tests that use newTestHead
- Add cleanup for heads created with NewHead directly in restart
  patterns (e.g., restartHeadAndVerifySeriesCounts, startHead)
