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).

Removes some unneeded calculations and threads the remaining.
Threading was previously removed to avoid overhead issues with small
boards. This is no longer needed with the thread pool implementation
Fixes https://gitlab.com/kicad/code/kicad/issues/12131
Thread pools are long-lasting executors that have close to zero overhead
when launching new jobs. This is advantageous over creating new threads
as we can use this for threading smalling jobs and smaller quanta. It
also avoids the heuristics needed to determine the optimal number of
threads to spawn
1) Drop tiny islands which might cause connection problems.
2) Cleanup some dead code in filler
3) Don't estabilish a connection to an island that is fully covered
by whatever its connecting to.

1) Generate SHAPE_POLY_SET triangulation by outline so they can be
shared between connectivity system and other clients.
2) Don't add items to connectivity when reading board; we're going
to do a total rebuild anyway.
3) Use multithreading when caching triangulation.
When we reset m_connAlgo, we need to lock the data mutex otherwise,
yields to the system may sometimes issue calls back to invalid data
until m_connAlgo has finished rebuilding

Some tools move only preview items while keeping the real items
hidden. Those tools must use this new offset parameter.
Other tools move the real items. Those tools can ignore this
parameter (which will default to {0,0}).

1) Implement more robust connection checking so we don't decide very
short segments with both endpoints within a single track are connected
at both ends.
2) Make use of the IS_DELETED flag to perform iteration during dryRun
so that all deletions to be made are flagged.
Fixes https://gitlab.com/kicad/code/kicad/issues/8883
Use the connecting straight tracks even if not exactly parallel - allow
an error margin configurable in ADVANCED_CFG (default 1 degree). Also
be less strict about end point matching and use the width of the track
as the criteria to determine suitability.
Finally, delete any short lengths of track at the end of the operation
and amend the arc end points to keep connectivity.

Commit 6ffb721 detects vias connected on only one layer.
But the DRC diag (marker position and error message) were not correctly initialized
for this new test.
