Future support for Gen11 devices using IGC v1 in Ubuntu

[mckees]

Hello!

We noticed the release notes for IGC 2.1.12 state that support will be dropped for Gen11 and earlier. We'd like to find a way to continue supporting IGC1 (and by extension a legacy version of compute runtime) in Ubuntu, but we would need the llvm version to continue to be updated regularly.

Questions:

1. Will it be possible to update IGC1's llvm dependency regularly?
2. If not, how can we expect a lack of IGC + compute runtime to impact functionality of the graphics stack on Gen11 and before?
