Simplify parsing of HW requirements and add missing ones

[happz]

It turned out some requirements were left out and nothing was parsing them. The "maximal" unit test was incorrect and did not report this.

The patch

• adds parsing for missing requirement groups (gpu, device),
• several individual requirements were also missing,
• simplifies parsing of groups of constraints, providing helpers to avoid repetition,
• and fixes the test guarding this.

Pull Request Checklist

@happz thank for an update! Would you consider adding requirement group "device" as described in https://tmt.readthedocs.io/en/stable/spec/hardware.html#device ? In some cases like Driver Update Program we do not classify devices as gpu/network/etc but need to find systems by device's ID only

device should be one of the refactored and completed requirements, see https://github.com/teemtee/tmt/pull/2928/files#diff-1f37ee00a19e467a4f192fb6c06f6f3cce3b9e460896ed5397a89054bf58d085R1371

Note that this patch focuses on shared library part of HW requirements - the implementation for Beaker provisioning will follow soon.
