Started with TARCAP because they're simple, but will follow and extend
this to the other flight plans next.
This works by building navigation meshes (navmeshes) of the theater
based on the threat regions. A navmesh is created for each faction to
allow the unique pathing around each side's threats. Navmeshes are built
such that there are nav edges around threat zones to allow the planner
to pick waypoints that (slightly) route around threats before
approaching the target.
Using the navmesh, routes are found using A*. Performance appears
adequate, and could probably be improved with a cache if needed since
the small number of origin points means many flights will share portions
of their flight paths.
This adds a few visual debugging tools to the map. They're disabled by
default, but changing the local `debug` variable in `DisplayOptions` to
`True` will make them appear in the display options menu. These are:
* Display navmeshes (red and blue). Displaying either navmesh will draw
each navmesh polygon on the map view and highlight the mesh that
contains the cursor. Neighbors are indicated by a small yellow line
pointing from the center of the polygon's edge/vertext that is shared
with its neighbor toward the centroid of the zone.
* Shortest path from control point to mouse location. The first control
point for the selected faction is arbitrarily selected, and the
shortest path from that control point to the mouse cursor will be
drawn on the map.
* TARCAP plan near mouse location. A TARCAP will be planned from the
faction's first control point to the target nearest the mouse cursor.

If the package is not flying into the threat zones of significant air
defenses there's no need for SEAD, and packages not near enemy airbases
do not need escorts. Prune these flights from the package to save
aircraft.
Not converting all at once so I can prove the concept. After that we'll
want to cover all the cases where an int distance or speed is a part of
the save game (I've done one of them here with `Flight.alt`) so further
cleanups don't break save compat.

Moves all TOT planning into the FlightPlan to clean up specialized
behavior and improve planning characteristics.
The important part of this change is that flights are now planning to
the mission time for their flight rather than the package as a whole.
For example, a TARCAP is planned based on the time from startup to the
patrol point, a sweep is planned based on the time from startup to the
sween end point, and a strike flight is planned based on the time from
startup to the target location. TOT offsets can be handled within the
flight plan.
As another benefit of theis cleanup, flights without hold points no
longer account for the hold time in their planning, so those flights are
planned to reach their targets sooner.
As a follow up TotEstimator can be removed, but I want to keep this low
impact for 2.3.2.

This was made largely pointless in 2.2, since the AI won't plan a dozen
CAPs 300nm from the front line any more. Culling flights mostly just
confuses players and breaks the planning AI.
If we do want to limit flight counts, we need to do that by limiting
flight counts. The AI will try to put their aircraft as close to the
mission as possible, so culling will do very little to stop them from
spawning 50 flights at the front-line attached airfield.

We shouldn't be constructing these by hand, and the first argument is
not the value of the string. I'm not really sure why the current code
works at all. We probably do this in other places and should clean that
up, but for now this should fix Tauntaun.
