The spec says that VkGraphicsPipelineCreateInfo::pTessellationState is
ignored and may be an invalid pointer in some cases. When ignored,
patch the pCreateInfo with `pTessellationState = NULL`, so the encoder
doesn't attempt to encode an invalid pointer.
Tested in Borealis, with debug build of venus, with a minimal test app
that sets `.pTesselationState = 0x17`. Pre-patch, the app crashes;
post-patch, the app works.
