SkStrike becomes SkScalerCache. It will eventually externalize
the memory accounting to SkStrikeCache::Node because the amount of
memory used by the scaler cache, and the overall strike cache memory
usage must be kept in sync.

SkTPin still exists. We can't use std::clamp yet, and even when
we can, it has undefined behavior with NaN. SkTPin is written
to ensure that we return a value in the [lo, hi] range.
