Delete .GuardCF library build (#110671)
Based on measurements on the ASP.NET perf infra (BasicWebApi and TodosApi), using the GuardCF libraries in non-guard context doesn't have measurable impact on throughput. The impact on size is negligible. We can just have it enabled unconditionally on the native runtime bits.
