Display driver version mismatch when IGX users on kernel <= 1012 do an upgrade

[Noah Wager]

IGX users on the linux-nvidia-tegra-igx metapackage ABI version <= 1012 will run into a display driver issue if they run `sudo apt upgrade`. This happens because recent versions of that metapackage install the r36.3.0 driver version used for Jetson, whereas IGX r36.3 userspace expects r36.3.1.

To avoid this, we recommend IGX users install the branched metapackage linux-nvidia-tegra-igx-r36.3.1, but the IGX BaseOS 1.0 image was already released with linux-nvidia-tegra-igx 1012, before linux-nvidia-tegra-igx-r36.3.1 was available. This means users on the 1.0 image with the 1012 kernel might break the display driver versioning if they upgrade to the newer versions using Jetson drivers.

To fix this issue, we will change the linux-nvidia-tegra-igx metapackage to install r36.3.1 drivers so IGX upgrades still install the correct drivers. Specifically, linux-nvidia-tegra-igx will transition to linux-nvidia-tegra-igx-r36.3.1, and the unbranched "linux-nvidia-tegra-igx" package name will be deprecated (i.e. a transitional package).

This will shift the issue onto Jetson installs, as upgrades will install IGX drivers and cause a mismatch in the other direction, so we recommend Jetson users install linux-nvidia-tegra-igx-jetson going forward.

If an upgrade has already been performed and the issue is present, users just need to get terminal access to their device and `sudo apt install` the correct metapackage branch, which will automatically install and replace the necessary components. After that, a reboot should fix the issue.
