[Any Drill][Fixed] Do not overwrite other drill pairs with pth_id

[nguyen-v]

This PR fixes the overwriting of non through-hole drill pair files when pth_id is specified.
I've also modifed the YAML files for the test cases (non-legacy) so that the default pth_id and npth_id are explicitly specified. Without the fix, it will overwrite the files which results in the test failing.
I'm not sure how to modify the legacy YAML files for this test, I've tried to add pth_id and npth_id but doesn't seem to change anything, I assume the legacy way of generating drill files did not have a function to rename the files? In this case it would be a non-issue

I don't think you need to modify the YAML files, please verify it, I did a quick check and these changes aren't needed.

With the modified YAML file, the tests fail without the fix and pass with the fix. Wouldn't we need to modify them to catch the overwriting case, or is fixing the root of the problem enough?

Then modify one of them, lets say drill_single so we get a mix
