This PR adds support for adding a specific set of mappings from Zed
syntax tokens to VS Code scopes for a particular theme family.
We can use this as a fallback when we aren't otherwise able to rely on
the mappings in the theme importer, as sometimes it isn't possible to
make a specific enough matcher that works across all of the themes.
Release Notes:
- N/A
This PR improves the approach we use to match syntax tokens between Zed
and VS Code in the `theme_importer`.
We now use the list of scopes assigned to each Zed syntax token to rank
the possible candidates in the VS Code and then pick the candidate with
the highest rank.
So far this has proved to provide better colors across the board, but
we'll continue to refine the matching over time.
Release Notes:

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 updates the `theme_importer` with support for parsing theme
files containing comments.
Up until now we've been manually removing comments from the VS Code
theme files.

When this feature is set the `themes` module won't be compiled.
This allows us to run the `theme_importer` even when the `themes` module
has compile errors in it.
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).
Release Notes:
- N/A
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.
