Geometry dispose doesn't delete buffers

[dmnsgn]

See glTF example where changing models keeps increasing the numbers of buffers.

[dmnsgn]

Current workaround:

function cleanUpGeometryBuffers(ctx, geometry) {
  if (geometry._indices.buffer) ctx.dispose(geometry._indices.buffer)

  Object.values(geometry._attributes).forEach((attribute) => {
    if (attribute.buffer) ctx.dispose(attribute.buffer)
  });
}

v4: we have no dispose implemented anywhere

New World and RenderEngine classes implements dispose by calling dispose on all the system

Added option to pass entities to render engine too in 12adc6c
