Gracefully handling texture creation failure

Gracefully handling texture creation failure

For many reasons, something can go wrong within GrGpuGL::onCreateTexture() and fail to create the backing store's texture. Instead of crashing, we can handle this gracefully and simply render the page without the filter(s) applied.

Adding enne@ to have an owner as reviewer.

LGTM.

Note that this is a subset of https://codereview.chromium.org/315913002.
I think we should land this smaller subset, since it'll be more likely to be
mergeable to M36, but also land the larger fix.

lgtm2, although an instant trace event would be nice as a warning that something
bad was happening.
