Cleanup: Delete unused code

Small UI Fixes

* Fixed comment about the "Surface" panel. It's used after all
(as a parent for two others). Adjusted comment to make that
more obvious.

* Don't show decorators on the Parent Relations panel.
None of those settings should be driven/animated.
Maybe we put it back for overrides later though?

Cleanup: Remove all old panels that Annotations will not be using

UI Tweak: Disable property split for GP Layers panel

There's just a single property here (opacity) under a
list widget that spans the full width of the panel.
It's not really worth having the half-size widget here.

Decouple GP Object's "Layers" panel from that used for "Annotations"
