Revert "Don't send strike with no pending glyphs"

This reverts commit 9e081d164c816bdf6df9c1f11b6928dab08c753c.

Reason for revert: Spike in cache misses: chromium:996636


Original change's description:
> Don't send strike with no pending glyphs
> This changes tracks the strikes to send as a set of pointers
> to SkGlyphCacheState instead of as descriptors. This removes a descriptor
> lookup allowing rapid calculation of the actual number of strikes to send.
> Knowing the number of strikes with changes allows us to remove sending a boolean
> if strike has no pending glyphs.
