Improve error message for duplicate parameters Duplicate parameters are banned both overall in strict mode and also in arrow functions. Our error message for both cases blamed strict mode, which is confusing. This patch fixes the message to point to arrow functions as a possible source as well.

[parser] Declare variables through ExpressionScope Use variable tracking from ExpressionScopes rather than the PatternRewriter and PreParserExpression::variables_ to declare variables. We only figure out that variables are non-simple parameters once we see the first non-simple parameter. This still uses the pattern rewriter to make variables non-simple (kLet instead of kVar).
