Replaced std::exit() with return Carbon::ErrorOr for expected errors like invalid syntax (#1120)
* Replaced std::exit() with return llvm::Expected/llvm::Error<T> for expected errors like invalid syntax.
* Use llvm::formatv() for formatting lexer error messages.
x
* Addresed merge errors.
* Fixed impl scope.
* Made ErrorBuilder::operator<< nodiscard, to catch code forgetting 'return' in 'return FATAL_COMPILATION_ERROR()'.
* FatalComplationError() -> ParseAndLexContext::RecordLexerError().
Other usages of ERROR_TOKEN in lexer.lpp were actually supposed to be END_OF_FILE.
* Update executable_semantics/syntax/parse_and_lex_context.h
