This PR adds support for capabilities for the extension process API.
In order to use the process API, an extension must declare which
commands it wants to use, with arguments:
```toml
[[capabilities]]
kind = "process:exec"
command = "echo"
args = ["hello!"]
```
A `*` can be used to denote a single wildcard in the argument list:
```toml
[[capabilities]]
kind = "process:exec"
command = "echo"
args = ["*"]
```
And `**` can be used to denote a wildcard for the remaining arguments:
```toml
[[capabilities]]
kind = "process:exec"
command = "ls"
args = ["-a", "**"]
```

- N/A

This PR updates the `extension` crate's tests to use a dedicated test
extension for its tests instead of the real Gleam extension.
As the Gleam extension continues to evolve, it makes it less suitable to
use as a test fixture:
1. For a while now, the test has failed locally due to me having `gleam`
on my $PATH, which causes the extension's `get_language_server_command`
to go down a separate codepath.
2. With the addition of the `indexed_docs_providers` the test was
hanging indefinitely.
While these problems are likely solvable, it seems reasonable to have a
dedicated extension to use as a test fixture. That way we can do
whatever we need to exercise our test criteria.
The `test-extension` is a fork of the Gleam extension with some
additional functionality removed.
