Defer mip-mapping until lazy proxy instantiation
- Remove some checks for truly impossible failures (levelCount < 0)
- Use helper method to predict number of mips, then verify correct
results in the lambda.
- Split up SkMipMap::Build with a CanBuild helper, so GPU code can
predict success/failure accurately.
- This is going to simplify the case where we need to change the
config for unsupported formats.
