Math: Complete Matrix4f w/ Vec[234]f and adopt it throughout Quaternion, Ray, AABBox, Frustum, Stereo*, ... adding hook to PMVMatrix

Motivation was to simplify matrix + vector math usage, ease review and avoid usage bugs.

Matrix4f implementation uses dedicated float fields instead of an array.

Performance didn't increase much,
as JVM >= 11(?) has some optimizations to drop the array bounds check.

AMD64 + OpenJDK17
- Matrix4f.mul(a, b) got a roughly ~10% enhancement over FloatUtil.multMatrix(a, b, dest)
- Matrix4f.mul(b) roughly ~3% slower than FloatUtil.multMatrix(a, b, dest)
- FloatUtil.multMatrix(a, a_off, b, b_off, dest) is considerable slower than all
- Matrix4f.invert(..) roughly ~3% slower than FloatUtil.invertMatrix(..)

RaspberryPi 4b aarch64 + OpenJDK17
- Matrix4f.mul(a, b) got a roughly ~10% enhancement over FloatUtil.multMatrix(a, b, dest)
- Matrix4f.mul(b) roughly ~20% slower than FloatUtil.multMatrix(a, b)
- FloatUtil.multMatrix(a, a_off, b, b_off, dest) is considerable slower than all
- Matrix4f.invert(..) roughly ~4% slower than FloatUtil.invertMatrix(..)

Conclusion
- Matrix4f.mul(b) needs to be revised (esp for aarch64)
- Matrix4f.invert(..) should also not be slower ..
