LibWeb: Simplify StyleValue API now that auto isn't a length

Browse source 
Now that LengthStyleValue never contains `auto`, IdentifierStyleValue is
the only type that can hold an identifier. This lets us remove a couple
of virtual methods from StyleValue.

I've kept `has_auto()` and `to_identifier()` for convenience, but they
are now simple non-virtual methods.
