Net tie groups are currently separated by comma. But comma is also an
allowed, albeit rare character for pad names. To allow pad names with
commas in net tie groups, the group definition must be escaped with a
forward slash for commas (and forward slashes).
Pad 1,2
Pad 2,3
Net-tie group "1\,2,2\,3"

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).

pad of a given number.
Also improves other DRC logic to tighten up the net-tie rules now that
we know which pads are allowed to short with which other pads.
Also removes the "Overlapping pads" DRC violation now that we know
whether or not overlapping pads in a net-tie footprint constitute a
short.
Fixes https://gitlab.com/kicad/code/kicad/issues/12506
Each pad group is allowed to short nets with other pads in its group.
Legacy footprints with the "net tie" keyword hack will get a single
group auto-created with all the footprint's pads in it.
DRC and the router now allow a track to collide with copper graphic items
while entering a net-tie pad as long as the closest point in the collision
is within the pad.
DRC (and the footprint checker) now check for copper items in the
footprint shorting pads which are not in the same pad group.

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.
