Build property trees for the HUD layer when using layer lists
When using layer lists in the compositor (aka, SPV2 mode), the hud
layer created in the layer tree host will not have property tree
nodes set. This patch ensures these nodes are set by the layer tree
host.
With this patch, running with the following flags does not crash:
--enable-slimming-paint-v2 --show-paint-rects
