As mentioned in https://github.com/boa-dev/boa/pull/2848#issuecomment-1518909512, this uses our new default ICU4X data to replace `char::is_start` and `char::is_continue` from the `boa_unicode` crate with the [`icu_properties`](https://crates.io/crates/icu_properties) crate.
Note that this doesn't deprecate `boa_unicode` yet, since that'll require some discussion about how to proceed with a now unused sub-crate.
We currently use `unicode_normalization` to handle the `String.prototype.normalize` method. However, the crate doesn't support UTF-16 as a first class string, so we had to do some hacks by converting the valid parts of a string to UTF-8, normalizing each one, encoding back to UTF-16 and concatenating everything with the unpaired surrogates within. All of this is obviously suboptimal for performance, which is why I leveraged the `icu_normalizer`, which does support UTF-16 input, to replace our current implementation.
Additionally, this allows users to override the default normalization data if the `intl` feature is enabled by providing the required data in the `BoaProvider` data provider.
This PR upgrades ICU to 1.2.
Unfortunately we still have some breaking changes, so this is being handled in https://github.com/unicode-org/icu4x/issues/3332

This Pull Request closes#1975. It's still a work in progress, but tries to go in that direction.
It changes the following:
- Adds a new `TryFromJs` trait, that can be derived using a new `boa_derive` crate.
- Adds a new `try_js_into()` function that, similarly to the standard library `TryInto` trait
Things to think about:
- Should the `boa_derive` crate be re-exported in `boa_engine` using a `derive` feature, similar to how it's done in `serde`?
- The current implementation only converts perfectly valid values. So, if we try to convert a big integer into an `i8`, or any floating point number to an `f32`. So, you cannot derive `TryFromJs` for structures that contain an `f32` for example (you can still manually implement the trait, though, and decide in favour of a loss of precision). Should we also provide some traits for transparent loss of precision?
- Currently, you cannot convert between types, so if the JS struct has an integer, you cannot cast it to a boolean, for example. Should we provide a `TryConvertJs` trait, for example to force conversions?
- Currently we only have basic types and object conversions. Should add `Array` to `Vec` conversion, for example, right? Should we also add `TypedArray` conversions? What about `Map` and `Set`? Does this step over the fine grained APIs that we were creating?
Note that this still requires a bunch of documentation, tests, and validation from the dev team and from the users that requested this feature. I'm particularly interested in @lastmjs's thoughts on this API.
I already added an usage example in `boa_examples/src/bin/derive.rs`.

This Pull Request enables support for `no_std` targets on some of our sub-crates. I intentionally left out `boa_ast` and `boa_cli` because they're the largest crates we have after `boa_engine`.
`boa_gc` is a monster on its own, because we'll need to design a `no_std` multithreaded GC.
Anyways, this changes the following:
- Adds support for `no_std` on `boa_unicode`.
- Adds support for `no_std` on `boa_profiler`.
- Adds support for `no_std` on `boa_interner`.
- Adds support for `no_std` on `boa_icu_provider`.

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.
