Fix 10 ClangTidy - Performance findings in //depot/google3/third_party/quic/.

These fixes are automatically created by various analysis tools, but their application in this CL has been manually triggered.  See go/code-findings-fixes.

* passing result of std::move() as a const reference argument; no move will actually happen (4 times)
* use absl::StartsWith instead of find() == 0
* use ZeroDuration() for zero-length time intervals (5 times)
