Debarshi Dutta 69ef86e627 gpu: nvgpu: move safe code HAL files to fusa
This patch moves all the safe static and non-static functions as well
as its dependencies such as static declared structs into files with
_fusa.c extension. If the original file is left with no functions
remaining then the file is deleted.

Added changes in Makefile, Makefile.sources, nvgpu-hal-new.yaml for
compilation.

Jira NVGPU-3690
