a7330cf469 Improve group movement by distributing units around the target.
This improves pathfinding feel as units no longer try to clump on a particular point. However, can lead to oddities if there's a lot of impassable terrain around.

Closes #7791

0308c2390a Rework the pathfinder path computation setup for threading.
Essentially reverts D1918 / d592bf9cb6.
Instead of copying path requests to workers, setup the result vector,
then setup an index, and compute 'in-place'.
To send messages, the result vectors are read in order. This makes the
order trivially constant no matter how many workers there are, and the
architecture overall makes it much easier to efficiently paralellise.

f6348b9617 Clean up header includes, add new forward declarations.
This cleans up many un-necessary header includes, either simply
providing nothing or forward declarations in their place.

No major compilation time change here, though this does reduce depencies
in some headers.

Also fix up old MacOS STL-include fixes that are no longer relevant.

375c319639 Improve ship pickup.
Improve unitAI: don't move if the requester can reach us and we are
close enough. This avoids an issue where ships moved more than necessary
when picking up many units.
Also improve requester UnitAI -> retry pickup if the target entity is
Idle.
Improve unitMotion: periodically recompute paths in "known bad path"
mode to adapt to moving targets.
Expose UnitMotion reachability to scripts and other code.

This adds a test map for some common and some tricky pickup cases, using
triggers.

32b2c01c7c Decouple long and hierarchical pathfinders to an extent.
Following 809f297707, this decouples the hierarchical pathfinder and the
long pathfinder. The long pathfinder was the class owning the
hierarchical pathfinder, which didn't particularly make sense and
resulted in some interface awkwardness.

At the moment, the long pathfinder still needs to hierarchical
pathfinder to compute paths (to make sure they are reachable).

809f297707 Move the Vertex Pathfinder to its own helper class
The vertex pathfinder was implemented directly in CCmpPathfinder,
instead of being a separate helper like the hierarchical pathfinder or
the long pathfinder.

This moves it to its own helper VertexPathfinder, which gets us ready
for D14 and pathfinder threading. Some struct definitions need to be
moved around.

128a603287 Use the terrain-only grid for terrain edges in the short pathfinder algorithm. This grid is updated on each terrain change, whereas the passability grid is updated once a turn. This caused OOS on rejoin, fixes #3292.
However, using the terrain-only grid reveals one discrepancy between the
short pathfinder (which uses unit radii) and the long one (which uses
unit clearances). So I implemented the change proposed by sanderd17 in
#3294, which is removing unit radius and using only the pathfinder
clearance. Refs #3294
Now some tweaking has to be done in the templates, so that units get a
passability class suited to their apparent size. In the meantime the
unit motion is quite bugged.
