This PR decouples the generation of licenses for the themes we ship from
the TypeScript theme definitions.

For now, we are embedding the license information for the themes in the
`theme_importer`, and emit a combined `LICENSES` file in the `theme`
crate whenever we import themes. This is also where we check that each
theme has a valid license.

We then use this `LICENSES` file when building up the global license
file for Zed.

This decoupling is one step towards us being able to delete the old Zed1
styles.

This removes one of the path dependencies in gpui that's only really
needed by `workspace` (which can work around lack of these
implementations by itself). In theory it should also improve build
scheduling (as gpui doesn't have to wait for main dependency of sqlez -
libsqlite3 - to finish it's 25 seconds-long build in release), though in
practice I didn't notice a substantial improvement.
Moreover `sqlez` was unused by `settings` too, so that's removed
as well.

According to
https://docs.digitalocean.com/products/kubernetes/how-to/configure-load-balancers/#ssl-certificates

you can specify whether to disable automatic DNS record
creation for the certificate upon the load balancer’s creation using the
do-loadbalancer-disable-lets-encrypt-dns-records annotation. If you
specify true, we will not automatically create a DNS A record at the
apex of your domain to support the SSL certificate.

This PR upgrades our version of `ctor` to v0.2.6.

We were previously using a fork that contained this fix:
https://github.com/mmastrac/rust-ctor/pull/295.

A new version of `ctor` has now been released with that change, so we
can switch back to the mainline version.

I scanned through the diff between versions (since we're upgrading from
effectively v0.1.20) and didn't notice anything that seemed obviously
breaking:

My contact over at nushell told me they are finally getting some fixes
in on the tree sitter repo, as they have an enthusiastic user running
around opening PRs - figured it would be good to bump this again, since
it wasn't in a great place before.

Release Notes:

- Bumped `nu` tree sitter dependency

Adding guest roles led us down a rabbit hole where we'd have liked to
rely on a
side-effect of activating a window in tests; but the test window didn't
implement that.

Looking into that, I realized our TestWindow wasn't doing a great job of
emulating the MacWindow, so this makes the two more similar.

This PR iterates on the design of the project search bar:

- Mode selections have been updated to use `ToggleButton`s
- Spacing has been added between the various elements.

Release Notes:

- Improved the look of the project search bar.

Release Notes:

- Show search input field wider for narrow panes

This PR updates the project search empty state to use the same
background color as the editor.

Release Notes:

- Updated the background color of the project search's empty state to
match the editor background.

This PR updates the welcome screen to use the same background color as
the editor.

Release Notes:

- Updated the background color of the welcome screen to match the editor
background.

This PR introduces Tinted button styles and the `selected_style` field
on buttons to allow replicating the previous design of titlebar call
controls. It also updates the styles of the titlebar controls.

### Creating a tinted button:

```
Button::new("accept-cta", "Accept")
    .style(ButtonStyle::Tinted(TintColor::Accent))
    .on_click(...)
```

Ths button will always be tinted blue.

### Creating a button that becomes tinted when selected::

```rust
IconButton::new("screen-share", Icon::Screen)
    .style(ButtonStyle::Subtle)
    .selected(is_screen_sharing)
    .selected_style(ButtonStyle::Tinted(TintColor::Accent))
    .on_click(...),
```

This button will be flat/subtle by default, but be tinted blue when it
is `selected`.

Note: There appears to be some issue where `is_deafened` isn't
activating correctly, making the speaker icon not toggle when selected.

Release Notes:

- Restore call control styles to a similar look to Zed 1.

This PR makes it so we respect the setting to show/hide the assistant
and chat panels.

Resolves https://github.com/zed-industries/community/issues/2370.

Release Notes:

- Fixed an issue where the settings to show/hide certain panels were not
respected.

Release Notes:

- Fixed a leak that would prevent projects from being automatically
unshared or left when closing the corresponding window.

Release Notes:

- Fixed a bug that would shrink the pane when following someone.

Add a `workspace::DeploySearch` action and use it as a default for
"cmd-shift-f" binding. This action opens existing search tab if it
exists, or creates a new one otherwise. `workspace::NewSearch` action is
still available and always opens an existing search tab.

Release Notes:

- Added a `workspace::DeploySearch` action and use it as a default for
"cmd-shift-f" binding. `workspace::NewSearch` action is still available
and always opens an existing search tab.

Needed for debugging some fun following tests
