Fixed some bugs in render graph 

- Changed the eid buffer for instanced rendering to a vec2 (potentially vec3 or 4), to pass other types of data like light layer index. 
- Renamed some render graph nodes and subpasses. Added a dummy render pass to transition the scene to read only optimal.
- offscreen buffer resource now transitions to eShaderReadOnlyOptimal instead of eGeneral
