/**
* Verify if the provided vendor and version supports RenderEffect caching
* behavior.
*
* Certain Open GL Driver implementations run into blocking scenarios
* with Fence::waitForever without a corresponding signal to unblock
* This happens during attempts to cache SkImage instances across frames
* especially in circumstances using RenderEffect/SkImageFilter internally.
* So detect the corresponding GL Vendor and driver version to determine if
* caching SkImage instances across frames is supported.
* See b/197263715 & b/193145089
* @param vendor Vendor of the GL driver
* @param version Version of the GL driver from the given vendor
* @return True if a RenderEffect result can be cached across frames,
* false otherwise
