Fix nearby fonts for DxEngine again (#16323)

The nearby font loading has to be outside of the try/catch of the
`_FindFontFace` call, because it'll throw for broken font files.
But in my previous PR I had overlooked that the font variant loop
modifies the only copy of the face name that we got and was in the
same try/catch. That's bad, because once we get to the nearby search
code, the face name will be invalid. This commit fixes the issue by
wrapping each individual `_FindFontFace` call in a try/catch block.

Closes #16322

## Validation Steps Performed
* Remove every single copy of Windows Terminal from your system
* Manually clean up Cascadia .ttf files because they aren't gone
* Destroy your registry by manually removing appx references (fun!)
* Put the 4 Cascadia .ttf files into the Dev app AppX directory
* Launch
* No warning ✅
