Auto merge of #15438 - asajeffrey:url-serializable-origin, r=jdm

Add ImmutableOrigin to allow for serializing origins

<!-- Please describe your changes on the following line: -->

This PR adds a serializable type `ImmutableOrigin` and a non-serializable type `MutableOrigin`. The immutable type represents an origin with `null` domain, and the mutable type represents an origin with a mutable domain. This separation is needed for implementing setting `document.domain`.

<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: -->
- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [X] These changes fix #14892.
- [X] These changes do not require tests because it's a refactoring which will enable other features.

<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->
