viz: Preserve root pass remapped ID when the surface ID changes

This change preserves the root render pass' remapped ID when a surface
is cloned with a new local surface ID (LSID).

We currently preserve damage (via prev_frame_index) in the case when a
surface is cloned with a new LSID. This works well for the root surface
the output device owns the root surface. However, when
renderer_allocates_images, then the root surface will appear as an
entry in SkiaRenderer::render_pass_backings_, which is a map keyed by
render pass ID. When the LSID changes, we could end up with a frame
that assumes that content from the previous frame is still present
(via preserved damage), but we have a new root pass ID.
