preprocessor: reject a malformed macro call instead of silently accepting

Address review feedback: when the macro-argument scan reaches an
unexpected token (in particular the EOF from an unterminated call),
ConsumeAndParseMacroCall now returns an InvalidArgumentError and the
caller records it as a preprocessor error at the call site, rather than
silently back-filling the arguments. An early ')' remains the legal way
to pass fewer arguments than parameters.
