This commit contains the ccache and python changes neccessary to migrate the ci.yml workflow to an azure kubernetes cpubuilder cluster.
Timings before and after the infra change are in the same ballpark (~10 mins).
Previously,
test/python/compile.py
was unnecessarily excluding the python site packages, which needed to be changed for the cluster.We also make use of
hendrikmuhs/ccache-action
now and use a key of${{ github.job }}-${{ matrix.torch-version }}
which works as intended: https://github.com/llvm/torch-mlir/actions/runs/12828039126/job/35771248056#step:7:4657
