[vulkan] Use simpler projection and z_up matrices

While both matrices had positive determinants in the first place, I find
the projection matrix easier to understand without all the negatives,
and having quake-x/vulkan-z positively parallel in the z-up matrix makes
that a lot easier to think about.

[vulkan] Add tan and cos perspective projection

The tan and cos versions allow specifying the fov directly from the tan
or cos of the half angle, useful for dealing with lights.

[vulkan] Move projection matrix code to its own file

And move more stuff over to simd.
