This PR reworks the way we define our third-party themes to make them
work as overlays on top of a base theme.

We introduce the concept of a `UserThemeFamily` that contains
`UserTheme`s. Rather than being an entire theme definition on their own,
a `UserTheme` just contains optional overrides for the values in a
`Theme`.

When resolving a `UserTheme`, we apply it on top of the base theme. Any
values not overridden in the `UserTheme` will fall back to the `Theme`
defaults.

Right now we are just using `UserTheme` to model third-party themes that
we distribute with the Zed binary. However, this same structure can also
be used to import arbitrary user themes (such as from a theme registry,
or even a theme blob from the settings file).

P.S. this is all completely different now

Ignore this PR for now.

This has a chance to speed up a build in case where e.g. we're
single-threaded in aarch64 build; at that point the x86_64 codegen can
take place. Also, MIR can probably be shared between the two
architectures, further reducing build time.

- Flesh out gpui2 test support
- Smoke test for event handling

This PR renames the `ThemeVariant` type to `Theme`.

This better reflects its purpose, as well as matches the same name as we
had before, which should make porting crates slightly easier.

Try to use notarytool to fix build problems

[[PR Description]]

Thanks @maxdeviant for all the help with this one 🫂 

- Adds the `theme_importer` crate
- Adds the ability to import themes in VSCode Format.
- Adds the `assets/themes/src` folder with source files for imported
themes
- Adds an initial set of themes: `andromeda`, `ayu`, `dracula`,
`gruvbox`, `night-owl`, `noctis`, `palenight`, `rose-pine`, `solarized`,
`synthwave-84`.

From the README:

## Usage

- `cargo run -p theme_importer` - Import the context of
`assets/themes/src`

---

## Troubleshooting

As the importer generates rust files, you may need to manually do some
cleanup in `registry.rs` and `themes/mod.rs` if you remove themes or
delete the `themes` folder in the theme crate.

---

## Required Structure

To import a theme or series of themes 3 things are required:

- `family.json`: A JSON file containing the theme family metadata and
list of theme variants
- `{theme_name}.json`: One theme json for each theme variant
- `LICENSE`: A license file for the theme family

### `family.json`

#### `name`

The name of the theme family. Avoid special characters.

This will be used for the theme family directory name (lowercased) and
the theme family name in the Zed UI.

Good:

- `Rose Pine`
- `Synthwave 84`
- `Monokai Solarized`

Bad:

- `Rosé Pine`
- `Synthwave '84`
- `Monokai (Solarized)`

#### `author`

The author of the theme family. This can be a name or a username.

This will be used for the theme family author in the Zed UI.

#### `themes`

A list of theme variants.

`appearance` can be either `light` or `dark`. This will impact which
default fallback colors are used, and where the theme shows up in the
Zed UI.

### `{theme_name}.json`

Each theme added to the family must have a corresponding JSON file. This
JSON file can be obtained from the VSCode extensions folder (once you
have installed it.) This is usually located at `~/.vscode/extensions`
(on macOS).

You can use `open ~/.vscode/extensions` to open the folder in Finder
directly.

Copy that json file into the theme family directory and tidy up the
filenames as needed.

### `LICENSE`

A LICENSE file is required to import a theme family. Failing to provide
a complete text license will cause it to be skipped when the import is
run.

If the theme only provices a license code (e.g. MIT, Apache 2.0, etc.)
then put that code into the LICENSE file.

If no license is provided, either contact the theme creator or don't add
the theme.

---

### Complete Example:

An example family with multiple variants:

```json
{
  "name": "Ayu",
  // When both name and username are available
  // prefer the `username (name)` format
  "author": "dempfi (Ike Ku)",
  "themes": [
    {
      "name": "Ayu Light",
      "file_name": "ayu-light.json",
      "appearance": "light"
    },
    {
      "name": "Ayu Mirage",
      "file_name": "ayu-mirage.json",
      "appearance": "dark"
    },
    {
      "name": "Ayu Dark",
      "file_name": "ayu-dark.json",
      "appearance": "dark"
    }
  ]
}
```

An example single variant family:

```json
{
  "name": "Andromeda",
  "author": "Eliver Lara (EliverLara)",
  "themes": [
    {
      "name": "Andromeda",
      "file_name": "andromeda.json",
      "appearance": "dark"
    },
    {
      "name": "Andromeda Bordered",
      "file_name": "andromeda-bordered.json",
      "appearance": "dark"
    }
  ]
}
```
