[PATCH 0/10 G/H][SRU][generic/aws/azure/gcp/oracle][L-R-M] Update the NVIDIA 455 driver

[Alberto Milone]

Update the NVIDIA 455 driver and drop the 435 series.

Also, provide a new virtual package, so that packagers
can specify a dependency on signed modules (as opposed to
the DKMS packages).

Each couple of patches covers one flavour: generic, aws, azure,
gcp, oracle.

This requires updating the debian/dkms-versions to match what is
in -proposed.
