MAINT: Add default constructor for global policy context

[david-cortes-intel]

Description

This PR adds a default destructor for the global policy context class.

It shouldn't make any kind of difference, since this class doesn't hold any members in need of destruction and it's used as a global variable, but it should decrease the number of false-positive findings from static code analyzers.

PR should start as a draft, then move to ready for review state after CI is passed and all applicable checkboxes are closed.
This approach ensures that reviewers don't spend extra time asking for regular requirements.

You can remove a checkbox as not applicable only if it doesn't relate to this PR in any way.
For example, PR with docs update doesn't require checkboxes for performance while PR with any change in actual code should have checkboxes and justify how this code change is expected to affect performance (or justification should be self-evident).
