LibJS: Add missing reserved words to Token::is_identifier_name()

Browse source 
This is being used in match_identifier_name(), for example when parsing
property keys - the list was incomplete, likely as some token types were
added later, leading to some unexpected syntax errors:

> var e = {};
undefined
> e.extends = "a";
e.extends = "a";
  ^
Uncaught exception: [SyntaxError]: Unexpected token Extends. Expected IdentifierName (line: 1, column: 3)

Fixes #3128.
