Implement Culling and FrontFace

This patch implements Culling and FrontFace on backends, and add tests too.

This test also verified that we couldn't invert FrontFace on Metal backend.
Otherwise, the tests would fail on all HWs.

But we do need to invert CCW/CW on OpenGL backend. Because Y axis is up in
OpenGL while Y axis is down in WebGPU.
