General invert hack using scaling w/ 1f/determinante gives +10%,
I would have thought this would have been optimized these days already on OpenJDK 17+

Additional Matrix4f perf improvement over FloatUtils
- invert (..) +14% faster for aarch64, 2% amd64
- mul(..) +14% faster for aarch64, 10% amd64

.. sure, these are all synthetic and only used for 'per object' affine stuff
like PMV matrix calculus when traversing through the world (picking, draw preparation ..).

But it was interesting to see where we are.

Now since this also at least demonstrates the 'new' code works and is not slower,
while exposing a nice OO math API - I probably will see how to replace FloatUtil in PMVMatrix
as well.
