cmake: Fix some Qt DLLs not being copied due to filename patterns

[RytoEX]

Description

Qt has some Release DLLs that end with the letter d:

• qdirect2d.dll
• qcertonlybackend.dll
• qopensslbackend.dll
• qschannelbackend.dll

As a result, they get caught by our simple check for if a DLL is a Debug DLL which just checks if the DLL ends with the letter d.

Extend that check to exclude these specific DLLs from being marked as Debug DLLs.

Motivation and Context

Noticed these files weren't being copied.

How Has This Been Tested?

Tested locally some time last year.

Annoying, but looks sensible to me.

Annoying, but looks sensible to me.

The only other way I could maybe think of would be to check every single filename for if a file exists with the same filename, but remove the d at the end, and see if there is still a file that exists with a d at the end of its name. That seemed painful, but I can explore that thought in the future.
