Vulkan: fix masked stencil clear Previously, masked stencil clear was done by clearing every stencil bit to the ClearValue & Mask. The correct behavior as implemented in this change is to clear only the bits that are set in Mask. This can only be done through a draw call, with ClearValue as the stencil reference, and Mask as the stencil write mask. Note: this change relies on the depthClamp Vulkan feature which is not available on ARM.
