Cherry pick fuzzer fixes back to M56

Cherry pick fuzzer fixes back to M56

This cherry-pick combines 3 fuzzer-fix CLs:

These two rolled into Chrome in https://codereview.chromium.org/2511733006 at 433297 on 11/18
https://skia-review.googlesource.com/c/4961/ (Remove accessRenderTarget call in SkGpuDevice ctor)
https://skia-review.googlesource.com/c/4929/ (Guard against instantiate & accessRenderTarget failures)

This one rolled into Chrome in https://codereview.chromium.org/2516183002 at 433454 on 11/20
https://skia-review.googlesource.com/c/4991/ (Add handling for instantiate failure up the call stack)

Together they address the fuzzer bugs:

crbug.com/665681 P1 (Crash in SkSpecialImage_Gpu::onAsTextureRef)
crbug.com/665621 P1 (Crash in GrGpuCommandBuffer::draw)
crbug.com/665500 P1 (Crash in GrDrawBatch::renderTargetUniqueID)

The fuzzer bugs were fixed by the first two patches but the third is going to be necessary too.

BUG=665681,665500,665621
