This Pull Request fixes/closes #1180. (I'll open a tracking issue for the progress)
It changes the following:
- Redesigns the internal API of Intl to (hopefully!) make it easier to implement a service.
- Implements the `Intl.Locale` service.
- Implements the `Intl.Collator` service.
- Implements the `Intl.ListFormat` service.
On the subject of the failing tests. Some of them are caused by missing locale data in the `icu_testdata` crate; we would need to regenerate that with the missing locales, or vendor a custom default data.
On the other hand, there are some tests that are bugs from the ICU4X crate. The repo https://github.com/jedel1043/icu4x-test262 currently tracks the found bugs when running test262. I'll sync with the ICU4X team to try to fix those.

Just some quality changes to improve the maintainability of the tester:
- Replaces `anyhow` with `color_eyre` to have a better output on errors/panics.
- Changes the ignore file to a TOML file and replaces all parsing logic with the `toml` crate.
- Adds a `ignored` field on all `Test`s to simplify run logic.
- Replaces the global `IGNORED` with an `ignored` argument on the CLI.
