Subject: [PATCH] Fix Codespaces prebuild after CMake upgrade and set policy in
 Mono (#88410)

The prebuild on Codespaces broke after the minimum CMake version was bumped in https://github.com/dotnet/runtime/pull/86530 because the container was still using Ubuntu 20.04 (Focal) which only has CMake 3.16.1.

Upgrade to Ubuntu 22.04 (Jammy) so we have a new enough CMake.

Also fix a missing policy in the Mono CMakeLists.txt that was accidentally removed.
