1. If we switch the TCS for one with a different number of output vertices, then the TES's gl_PatchVerticesIn value will change. We need to re-upload in this case. For now, re-emit constants whenever the TCS/TES are swapped out. 2. If there is no TCS, then we can't grab gl_PatchVerticesIn from the TCS info. Since it's a passthrough, we can just use the primitive's patch count (like the TCS gl_PatchVerticesIn does). Fixes KHR-GL45.tessellation_shader.single.max_patch_vertices and KHR-GL45.tessellation_shader.tessellation_control_to_tessellation_evaluation.gl_PatchVerticesIn.
