Revert "When creating emptyp MipMap proxies, don't instantiate them immediately."

This reverts commit 8242c5c199f5d04e4209222b265f9e27f7c55fa7.

Reason for revert: Hitting assert on intel bots on skbug6850overlay2.skp, SkASSERT(proxy->getUniqueKey().isValid()); in processInvalidProxyUniqueKey

Original change's description:
> When creating emptyp MipMap proxies, don't instantiate them immediately.
> 
> This chnages makes it match how we handle non mipped proxies where we
> don't actually instantiate them until we need to.
