Proof-of-concept to display unicode via the UC macro

[guidoism]

The current behavior displays an Any key with the text from the UC macro. This commit changes it to display the unicode character. The intent is to have a better experience if you are using the configurator just to view and tweak your keyboard.

There are several issues:

• You can't compile a keyboard with UC directly from the configurator
• You can't add unicode characters from the configurator
• I changed it to not upper case the character if the code point is above 255 which is arbitrary and potentially confusing
• I only made that change in one place, there are two other places where we do toUpperCase when the key is a single character but I don't understand what code path engages them
• It might not work if the UC macro is within another macro

Again, this is a proof-of-concept. It seems like a simple enough change to merge but I don't want to add anything that would be confusing to future coders due to the half-assed nature of my code. Please let me know if there's anything I can do, other than adding full unicode support, which I don't think I'd be able to actually accomplish.

So it's pretty cool. the question is how to integrate this. We could maybe add a new tab for unicode, but the bigger problem is I think we need API support in the form of data driven QMK that @skullydazed is working on.
