This PR adds the ability to warn in the `theme_importer` when a theme is
missing values.
Providing the `--warn-on-missing` flag to the `theme_importer` will
print a warning for missing theme value when printing the theme.
```sh
cargo run -p theme_importer -- --warn-on-missing
```

This PR fixes an issues where the hex colors in the generated themes
were not correct.
We're using the [`palette`](https://crates.io/crates/palette) crate to
perform the conversions, as this gives us accurate hex codes that match
the VS Code source themes.

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).

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.
