PMVMatrix: Defaults from direct NIO -> array-backed non-direct NIO: Reduced cycles 45% -> 5% (from GearsES2 100%)

- NIO direct access from Java is expensive

- default is now array-backed non-direct NIO,
  which guarantees array useage for Java computation (especially the inverse calculation)

- only update Mvi and Mvit if requested in the first place

- moved all local matrices to float[]
