This makes it clearer that the overrides are not inverses of each
other -- one overrides the flashing state and the other overrides
the connection state (to other zones, not to everything).
Also fixes a bug where we were failing to check the force-no-connect
for pads.
The implementation used to always check F_Cu and B_Cu, rather than
where the via started and ended (which will be different for blind/
buried vias and microvias).
Also adds some debugging to try to catch dangling pointers.
Also adds a cache for group bounding boxes (which will be expensive
to calculate for large groups).

Rather than moving the netname around, we want to keep the correct
number of netnames on a track such that there is always at least one
displayed on long tracks even when panning.
This reduces calculation time while keeping the netnames visible
Fixes https://gitlab.com/kicad/code/kicad/issues/12436
When panning, we should only redraw the netnames when they come into
view or go out of view. Caching the LOD provides this preventing
unneeded redraws while still redrawing on zoom changes

1) The highest priority zone that a via/pad collides with "owns" its
connectivity state. Once set, lower priority zones cannot change it --
and in fact, if they would have connected to it are forced not to.
2) The connectivity state goes with the zone fill state, and therefore
must be saved in the file.
3) Display of remove-unconnected's pads is no longer done in GetViewLOD()
(which isn't called for selected items), and is instead done in PCB_PAINTER.
This allows us to draw the full pad in outline mode when a via/pad is
selected which would otherwise only show the hole.
4) Note that in some cases this will still generate DRC errors -- in
particular when a via nearly collides with a higher priority zone it
won't get "owned" by that zone and may therefore have insufficient
clearance if said zone concludes it's unconnected and a subsequent
(lower priority) zone connects to it (causing it to now become flashed).

Previous test comparing start/end angles doesn't account for all cases.
This adds a more robust test to ensure all arcs are output in CW fashion

When building the connectivity database, we should not be using the
connectivity to check for shapes.
To make this deterministic, we introduce two flags (ALWAYS_FLASH and
NEVER_FLASH) that are used with connectivity building to determine
whether a pad is flashed for connectivity or not. ZONE <-> PAD/VIA
connectivity will be checked with ALWAYS_FLASHED and all other
connectivity will be checked with NEVER_FLASHED if they are marked for
potential annular ring removal. If they are not marked for removal,
they will be checked ALWAYS_FLASHED.
