Create TypeLiteral Constants

Originally mentioned by Arjan in the following post:

Map<String, String> headerMap = CDI.current().select(new TypeLiteral<Map<String, String>>() {}, HeaderMap.Literal.INSTANCE).get();

In a way for usability this is quite a step back, but a logical consequence of not allowing raw maps indeed. Maybe we can introduce something like a HeaderMap.TYPE to represent new TypeLiteral<Map<String, String>>() {} for Faces.Next.

A previous TCK challenge removed the ability to inject into raw Map types (as it was not spec defined), so TypeLiterals (introduced in 4.0) needed parameters to be injected properly into the parametrized types. It would be nice to have new constants to avoid the verbose code above.

@arjantijms @BalusC Could this be added to the 5.0 plan?
