Subject: [PATCH] gpu: nvgpu: enable run time log mask for safety debug and
 standard debug builds

- Enable /dev/nvgpu/igpu0/log_mask node on safey debug and standard
  debug builds which will help to enable log mask in run time.

- Enabled "CONFIG_NVGPU_SYSFS" flag for release and safety debug
  builds which will build sysfs files to enable
  /dev/nvgpu/igpu0/log_mask node for these builds

- Created "standard_debug" profile which is used to enable
  /dev/nvgpu/igpu0/log_mask node only for standard debug builds

Bug 3958585
