Russ Cox 24fa7544b0 runtime: fix spurious race using Ticker.Reset 
Ticker.Reset was added in CL 217362 in 2020.
It added the runtime helper modTimer, which is
analogous to startTimer and resetTimer but for tickers.
Unlike those, it does not contain a racerelease, which
means that code synchronizing by starting a ticker
will be diagnosed with a spurious race.

Add racerelease to modTimer and add tests of all
three racereleases (in startTimer, resetTimer, and modTimer).

Also do not call time.resetTimer from elsewhere in runtime,
since that function is only for package time. Use t.reset instead.

For #33184.

README 

runtime/race package contains the data race detector runtime library.
It is based on ThreadSanitizer race detector, that is currently a part of
the LLVM project (https://github.com/llvm/llvm-project/tree/main/compiler-rt).

To update the .syso files use golang.org/x/build/cmd/racebuild.
