Implementation for device query for validate/report names usage

[aktondak]

Problem solved by the commit

This PR implements new device queries for getting the list of validate test names and report names from each shim. This list is then used by xrt-smi to run appropriate validate tests and examine reports. The new query uses the same structures used by xrt-smi help printing to make xrt-smi behavior concurrent between help printing and running tests/reports.

Can one of the admins verify this patch?

It's odd that these functions are also defined in the base class but not as virtual. Maybe this is what you want, but it is not very clear.

[aktondak]

These functions are added to do away with virtual function definition in each derived class which I felt was not required. With this change, each shim derived class overrides the structures "validate_tests" and "examine_reports" in the constructors. These base class APIs then simply return those overridden structures in each derived class and base class structures in case of no shim. This change removes addition of 2 APIs in each shim and takes care of polymorphism in the class constructor itself.
