ASP-based solver: allow configuring target selection (#29835)
* ASP-based solver: allow configuring target selection
This commit adds a new "concretizer:targets" configuration
section, and two options under it.
- "concretizer:targets:granularity" allows switching from
considering only generic targets to consider all possible
microarchitectures.
- "concretizer:targets:host_compatible" instead controls
whether we can concretize for microarchitectures that
are incompatible with the current host.
* Add documentation
* Add unit-tests
