New strategy isolates all draw/don't draw decisions to the ViewGetLOD
routines, and all dimmed/not dimmed to PCB_RENDER_SETTINGS::GetColor.
The actual drawing in PCB_PAINTER is more-or-less conditon free.
Also adds new layers for pad and via hole walls so that they can be
controlled for high-contrast mode.
Also changes the drawing paradigm so that the pads are drawn even when
not on the high contrast layer, just in low contrast. The hole wall
is drawn in high contrast. This actually makes things clearer to the
user (although to be honest was done to keep from having to re-render
pads when the high contrast layer changes since we have two separate
layers now that we can adjut colours on).

Zone connections (even half-connections) should trigger the connected
logic in flashPads. This removes the double-standard for painting pads
and imposes thermal standoff based on the net connection to the pad if
it shares a net, not just if connected
New strategy is to draw the hole wall cylinder if the pad (or via)
isn't flashed on a particular layer. This is (1) more correct,
(2) keeps pads which aren't flashed on any layer from disappearing,
and (3) allows us to remove a bunch of the other special cases.
Or at least I think it does. The proof will be in the (lack of)
follow-on bug reports....
Also fixes a bug where via annular rings weren't highlighted in
high contrast mode.
Fixes https://gitlab.com/kicad/code/kicad/issues/7279
High contrast should not show the annular rings from other layers. Once
the ring is removed, we hide the annular when not focused on a flashed
layer

Also removes EditToolSelectionFilter which was misused in more places
than it was used correctly. The original point of the client filter
was to move the logic to the point of use, which the
EditToolSelectionFilter sort of obviated anyway.
