d5e3e6ae1b Add SkRacy
SkRacy<T> is a zero-overhead wrapper for a T, except it also
silences race warnings when TSAN is running.

Here we apply in several classes.  In SkMatrix and SkPathRef,
we use it to opportunistically cache some idempotent work.

In SkPixelRef, we wrap the genIDs.  We think the worst that
can happen here is we'll increment the global next-genID a
few times instead of once when we go to get another ID.

ea6e14a382 TSAN: use somewhat pithier SK_ANNOTATE_UNPROTECTED_READ.
This is a little bit better practice to be i than the existing SK_ANNOTATE_BENIGN_RACE, as UNPROTECTED_READ will only ignore reads, not writes.

Tag SkRefCnt::unique() as a safe unprotected read like SkOnce's double-checked locking.
