thread-local caches?
Here's another idea... these SkVMBlitter program caches are probably
best thread-local. If there are a bunch of threads doing the same work
with the same program, we don't need them fighting over that one slot in
the cache, and if there are a bunch of threads doing _different_ work,
they'll get the best cache behavior if they don't fight over slots in
the LRU with different programs. Either way, seems like a win?
(I've kept the try-acquire/release pattern just to make the focus of
this change more clear. We can fold it through more if we like it.)
