Subject: Disable sharing of stencil buffers across differently sized
 rendertargets

Due to revertapalooza, stencil buffers shared across differently sized rendertargets aren't getting cleared correctly. This CL disables the sharing until the clearing issues can be remedied. Note that stencil buffers should still be shared between identically sized render targets and should still be lazily allocated.
