Introduce the NVIDIA 520 UDA driver series

[Impact]
These releases provide both bug fixes and new features, and we would like to
make sure all of our users have access to these improvements.

See the changelog entry below for a full list of changes and bugs.

[Test Case]
The following development and SRU process was followed:
https://wiki.ubuntu.com/NVidiaUpdates

Certification test suite must pass on a range of hardware:
https://git.launchpad.net/plainbox-provider-sru/tree/units/sru.pxu

The QA team that executed the tests will be in charge of attaching the artifacts and console output of the appropriate run to the bug. nVidia maintainers team members will not mark ‘verification-done’ until this has happened.

[Regression Potential]
In order to mitigate the regression potential, the results of the
aforementioned system level tests are attached to this bug.

== 520.56.06 (UDA) ==

  * New upstream release:
    - Implemented support for over-the-air updates in the Proton and
      Wine NVIDIA NGX build. This feature is disabled by default and
      can be enabled by setting the "PROTON_ENABLE_NGX_UPDATER"
      environment variable to a value of "1".
    - Updated the Vulkan driver so that the following extensions no
      longer depend on nvidia-uvm.ko being loaded at runtime:
      + VK_KHR_acceleration_structure
      + VK_KHR_deferred_host_operations
      + VK_KHR_ray_query
      + VK_KHR_ray_tracing_pipeline
      + VK_NV_cuda_kernel_launch
      + VK_NV_ray_tracing
      + VK_NV_ray_tracing_motion_blur
      + VK_NVX_binary_import
      + VK_NVX_image_view_handle
    - Updated nvidia-installer to allow use of the "--add-this-
      kernel" feature by non-root users.
    - Updated nvidia-installer to display a more accurate progress
      bar when building the kernel modules.
    - Updated nvidia-installer to display a warning message if a
      Vulkan ICD loader is not detected.
    - Reworked nvidia-installer's support for DKMS: the kernel
      modules will now be optionally registered with DKMS after the
      installer has already built and installed them on its own.
      nvidia-installer will now register the kernel modules with DKMS
      by default when the dkms(8) utility is detected on the system.
    - Fixed a bug in the Vulkan driver which could lead to corruption
      in geometry and tessellation control shaders.
    - Added a new CUDA Debugger implementation for Pascal and newer
      architectures as a part of the driver package:
      libcudadebugger.so (previously released separately as "CUDA GDB
      Developer Preview").
    - Fixed a regression in 515.76 that caused blank screens and
      hangs when starting an X server on RTX 30 series GPUs in some
      configurations where the boot display is connected via HDMI.
    - Fixed a bug where Marvel's Spider-Man Remastered would
      sometimes crash with Xid 13 errors on Turing and later.
