This PR fixes some formatting issues in some of the `Cargo.toml` files.
I tried to fix most of these in #7126, but there were a few that I
missed.

This PR sorts the dependency lists in our `Cargo.toml` files so that
they are in alphabetical order.
This should make them easier to visually scan when looking for a
dependency.
Apologies in advance for any merge conflicts 🙈

The fonts we embed in Zed binary (Zed Sans & Zed Mono) weigh about 30Mb in total and we are cloning them several times during startup and loading of embedded assets (once explicitly in Zed and then under the hood in font-kit). Moreover, after loading we have at least 2 copies of each font in our program; one in .rdata and the other on the heap for use by font-kit.
This commit does away with that distinction (we're no longer allocating the font data) and slightly relaxes the interface of `TextSystem::add_fonts` by expecting one to pass `Cow<[u8]>` instead of `Arc<Vec<u8>>`. Additionally, `AssetSource::get` now returns `Cow<'static, [u8]>` instead of `Cow<'self, [u8]>`; all existing implementations conform with that change.
Note that this optimization takes effect only in Release builds, as the library we use for asset embedding - rust-embed - embeds the assets only in Release mode and in Dev builds it simply loads data from disk. Thus it returns `Cow<[u8]>` in it's interface. Therefore, we still copy that memory around in Dev builds, but that's not really an issue.
This patch makes no assumptions about the build profile we're running under, that's just an intrinsic property of rust-embed.
Tl;dr: this should shave off about 30Mb of memory usage and a fair chunk (~30ms) of startup time.
Release Notes:
- Improved startup time and memory usage.
- [x] Fill in GPL license text.
- [x] live_kit_client depends on live_kit_server as non-dev dependency,
even though it seems to only be used for tests. Is that an issue?

This essentially shaves off about 10% off of an incremental build after
project change and potentially more if you're changing stuff like
`welcome` that's very close to the `zed` crate in the dep graph. That's
because macro expansion takes place even in incremental builds it seems?
And zed (lib) + zed (bin) could take up to 4 seconds out of an
incremental build, which is a *lot* in a 10s build. In reality though it
shaves 1 second off of 5 seconds incremental 'welcome'/ 1s off of 10s
'project' builds.
Note that we had `assets` crate in the past (removed in #2575 /cc
@maxbrunsfeld), but this is a bit different, because `assets` is a
dependency of *just* zed and nothing else. We essentially cache macro
expansion results ourselves.
