[clang] Remove some `U+C2AD`s in `__cpp_multidimensional_subscript`

[JohnTitor]

Summary

The Builder.defineMacro("__cpp_multidimensional_subscript", "202110L"); line has
some U+C2ADs that shouldn't necessary here. So removed them.

It took me a moment, but this actually removes a 0xC2AD and not a 0x00AD. It's still correct, but I was wondering why no character was printed in the text -- 0xC2AD is not a defined Unicode character.

LGTM, but can you correct the patch title + summary when committing?

Oh, my editor said it 0x00AD, it's weird. Anyway thanks for clarifying.

Sure!
