Subject: [PATCH] [Offload] Add CMake cache to be used in AMDGPU bot

Adds initial CMake cache definition that is similar to what we use in
one of our production buidlbots. The goal is to consolidate the
configurations and make them accessible.
This cache file is a first step and to prepare for full pipeline
testing once the new bot comes online.
