fix normalized vector handling ( #6650 )
...
Although normalized vectors in FSO are supposed to stay normalized, occasionally small floating point errors can pop up. In most cases these do not cause a problem, but in certain cases these errors can rapidly accumulate and corrupt an otherwise well-behaved matrix. This can most easily be seen with daisy-chained dock sequences or docked ships with angled dockpoints.
This PR audits the usage of `vm_vector_2_matrix_norm` to re-normalize vectors in cases where floating point errors could accumulate. There are also a few new Assertions for extra vigilance.
Follow-up to #6596 . Fixes #6634 .

use vm_vector_2_matrix_norm on normalized vectors
...
Most places in the code that use `vm_vector_2_matrix` do so on already-normalized vectors. Changing these to `vm_vector_2_matrix_norm` avoids redundant normalization.

make internal variables in static rand unsigned.
...
several of the bitwise manipulations on signed integers are technically undefined behaviour.
I made the internal variables unsigned and the results are then converted to signed ints as before.
This should not actually change any observable results.
Did some cleanup as well, while I was at it.

Additional AI code, including stuff taking advantage of glide and sidethrust. Includes: Flag for allowing fighters to dodge vertically as well as horizontally, "stalemate detection" to help AI break out of circle fights and other stalemate situations, "glide attack" where AI fighters will use glide to fly away while shooting back at you, "circle strafe" where AI fighters will use sidethrusters to jink around while shooting, and an (incomplete) version of "glide strafe" that allows fighters/bombers to use glide to attack capital ships. All new stuff is off by default, and can be turned on with AI_Profiles flags.
