RE: Better error messages for context lost and SkiaVk

As in HWUI's CanvasContext::draw, check whether the context has been
abandoned at the beginning of a frame. Previously, RE never checked for
this, though it may have been responsible for other spurious failures,
such as "Unable to generate SkSurface".

When RE fails to generate an SkSurface/SkImage, query the backend to
determine which method to call to get more information about the
texture. This allows us to get meaningful information when running
SkiaVk.
