LibWeb: Introduce CalculatedOr type This is intended as a replacement for Length and friends each holding a `RefPtr<CalculatedStyleValue>`. Instead, let's make the types explicit about whether they are calculated or not. This then means a Length is always a Length, and won't require including `StyleValue.h`. As noted, it's probably nicer for LengthOrCalculated to live in `Length.h`, but we can't do that until Length stops including `StyleValue.h`.

/*
LibWeb/CSS: Update CalculatedOr API to use CalculationResolutionContext To be properly compatible with calc(), the resolved() methods all need: - A length resolution context - To return an Optional, as the calculation might not be resolvable A bonus of this is that we can get rid of the overloads of `resolved()` as they now all behave the same way. A downside is a scattering of `value_or()` wherever these are used. It might be the case that all unresolvable calculations have been rejected before this point, but I'm not confident, and so I'll leave it like this for now.

These are marked as deprecated rather than replaced outright as work will need to be done on the caller side to be made compatible with the new methods, for instance the new methods can fail to resolve (e.g. if we are missing required context), where the existing methods will always resolve (albeit sometimes with an incorrect value).

I've left a FIXME about implementing this in a more elegant and less layout-thrashy way, as that will require more architectural work.
