Confirmed that the change to bazel 4.2.1 even with clang-cl 12.0.1 still causes the following error optimizing external/com_github_grpc_grpc/_objs/grpc_lb_policy_xds_cluster_resolver/xds_cluster_resolver.obj
Appears that we have to now drop clang-cl for the time being until we get this sorted out. This is probably
closely related to clang dropping the default of -g2, and missing a unix clang flag in the corresponding
windows clang-cl compilation flags.

I see. I'll have to figure out how to fix this.

clang-cl has been suspended, if you wanted to merge main to pass CI
