feat(combat): Die carries the killing attack's smash direction

Browse Source 
Live filled Die's direction_relative_angle_xz, _angle_y and _force on
11,606 of 19,428 deaths. The values are the dir_angle_xz, dir_angle_y
(degrees, sent as radians) and dir_force parameters of the BasicAttack
that dealt the killing blow: per killing skill the triple is constant
(skill 1210: -25 degrees, force 12 on 540 of 549 kills; skill 10:
force 7 on 1,830 of 1,835), and deaths with no killer (5,948) never
have one. BasicAttack is the only behavior with these parameters apart
from one Grab. The client passes them to PerformSmashableDeath, which
throws the smashable's pieces that way; DLU sent 0.

The radians are rounded the way live did (-25 is 0xbedf66f3, 20 is
0x3eb2b8c3). Not covered: use_caster_velocity (one behavior, racing).

Check: smash crates and enemies with different weapons; the pieces fly
off to the side/up per weapon instead of straight out.
