[c++20] Implement tweaked __VA_OPT__ rules from P1042R1:
* __VA_OPT__ is expanded if the *expanded* __VA_ARGS__ is non-empty,
not if the original argument contained no tokens.
* Placemarkers at the start and end of __VA_OPT__ are retained just
long enough to paste them with adjacent ## operators. We never paste
"across" a discarded placemarker.
