Desktop X64DebugFabric job takes 20-30 min longer than all other jobs

Summary

The Desktop X64DebugFabric job takes 20-30 min longer than all other jobs we run. It sometimes hits the 60min limit and causes the test to timeout and need a re-run - which wastes another 60min.

We should figure out why it's taking so much longer and fix it (@jonthysell thinks there might be a cppwinrt flag we're missing) or we should increase the timeout limit to avoid manually requesting re-runs.

I can see in CI (which runs more build configurations) that desktop fabric builds timeout for other flavors too:
