Brian Salomon 9bc76d96f9 Change the meaning of GrBudgetedType::kUnbudgetedUncacheable. 
kUnbudgetedCacheable now means that the resource is never purged
until its unique key is removed.

This fixes an issue where a cached texture for a promise image
might get purged by cache pressure. This in turn could cause
Skia to call the promise image's Fulfill proc multiple times with
no intervening Release calls. The balancing Release calls would
occur, but the policy is that each Fulfill should be balanced by
Release *before* another Fulfill.

Update/add unit tests.
