Identify the active GPU using GL strings in multiple GPU situation.

Also, now we switch the multi_gpu_category setting for each entry to "active"
gpu as default (before was "primary" as default). It's more intuitive as mostly
we want to apply entries to the GPU that's in use.

This fixes a few bugs where we incorrectly apply the blacklist decisions
and workarounds to the GPU that's not in use.
