Action enabler control regular attacks.

Make regular attacks action enabler controlled via the new "Attack" action.
It had to be tile targeted. Making it units targeted would allow any unit at
a tile to forbid the action. (See the unreachable_protects server setting)

More rules, like attack from non native tile, should hopefully move to the
ruleset in follow up patches. Stronger "attack as action" integration is
also expected in follow up patches.

The actions "Capture Units", "Bombard" and "Explode Nuclear" have already
been split from regular attack. The fact that the regular attack now is an
enabler controlled action doesn't mean that it shouldn't be further split.

Note that action forcing still can block the non enabler controlled action
Occupy City. This makes it necessary to keep the force_* system internally.

See patch #7260
