Subject: video_core: draw Switch 2 task/mesh pipelines with VK_EXT_mesh_shader

While SET_MESH_CONTROL is on, a native draw binds a task program in the
vertex slot, its mesh program in the tessellation slot and a header-only
pass-through geometry program naming the per-primitive outputs. Translate
the first two as task and mesh programs with the mesh registers
(SET_MESH_SHADER_A/B, SET_MESH_INIT_SHADER) and that header, key their
pipelines by them, and build pipelines with task/mesh stages and no
vertex input, input assembly or tessellation state. The draw's vertex
count is the number of task workgroups: record vkCmdDrawMeshTasksEXT.
Enable VK_EXT_mesh_shader (task and mesh only) when the host has it; draws
are skipped without it, as they were before.
