Attempt to disable clear-as-draw-workaround on iOS PowerVR.

This workaround was modified here: https://chromium.googlesource.com/skia.git/+/43f8bf0f784f4182ed0fca9053ecf570caf7ad70

We have a report that this triggered a rendering regression on iOS. I believe this workaround was enabled on PowerVR due to issues on Android and not iOS.
