* shader_recompiler: handle fetch shader address offsets parse index & offset sgpr from fetch shader and propagate them to vkBindVertexBuffers * shader_recompiler: fix fetch_shader when offset is not present * video_core: propagate index/offset SGPRs to vkCmdDraw instead of offsetting the buffer address * video_core: add vertex_offset to non-indexed draw calls renamed fetch offset fields
