style: Fixup the hack added in #18867.
The declaration can indeed have the same id if it contains variables, or is a
CSS keyword value.
This was making a WPT test fail, so this is tested, though Servo's WPT import
didn't catch this for some reason.

This introduces DeclarationSource, to see if a declaration has been parsed or
set from CSSOM in a declaration block.
The Servo_DeclarationBlock_SetFoo and similar callers are changed to
DeclarationSource::CssOm because their semantics are more CSSOM-y, but it
shouldn't matter since they should all be checked before hand with
Servo_DeclarationBlock_PropertyIsSet.
Use pointer casts instead of tramsutes to raw::TraitObject
Casting `*const T` to `*const U` with `U: Sized` is allowed even if `T: ?Sized`. This safely extracts the data pointer out of a trait object, without relying on the memory representation of trait objects.

Make optional the usage of some unstable features
With `--no-default-features --features default-except-unstable`, more crates can now be compiled on stable Rust. This will help integrate them in rustc’s regression testing and compiler performance benchmarking.
