notification: Use interface availability to check for Windows version…

… suitability

• I confirm that I am the author of this code and release it to the SDL project under the Zlib license. This contribution does not contain code from other sources, including code generated by a Large Language Model ("AI").

Explicit version checks require application manifests on Win10, or an older version will be reported. Check for the toast notification history interface, which is only available on Win10+, and use that to determine if the Windows version is high enough to support notifications.

@madebr, can you check this on your test system?

Fixes #16017
Closes #16019

testnotification.exe now shows notifications on my Windows 10 system.

With transient notifications (T button in testnotification), the second notification causes a EXCEPTION_ACCESS_VIOLATION fatal error with the following stack:

Oof, some incorrect casting was causing memory to be clobbered when incrementing or decrementing the delegate refcount. Fixed.

The fun of dealing with COM from C code…

[madebr]

I cannot get the app to crash anymore, and I tried hard :)

Then let's merge this.
