Change a l public declarations to the `package` access level, accept for:
- The `LanguageServerProtocol` module
- The `BuildServerProtocol` module
- `InProcessClient.InProcessSourceKitLSPClient`
- `LanguageServerProtocolJSONRPC` (I would like to create a more ergonomic API for this like `InProcessSourceKitLSPClient` in the future, but for now, we’ll leave it public)
Unfortunately, our pattern of marking functions as `@_spi(Testing) public` no longer works with the `package` access level because declarations at the `package` access level cannot be marked as SPI. I have decided to just mark these functions as `package`. Alternatives would be:
- Add an underscore to these functions, like we did for functions exposed for testing before the introduction of `SPI`
- Use `@testable` import in the test targets and mark the methods as `internal`

When the client sends us `workspace/didChangeWatchedFiles` notification of an updated `.swift` file, we should refresh the other open files in that module since they might be referencing functions from that updated file.
If a `.swiftmodule` file has been updated, we refresh all the files within the package since they might import that module. Technically, we would only need to refresh files that are in module that are downstream of the updated module but we don’t currently have that information easily available from SwiftPM. Also, usually, if the client has a file from a low-level module open, he’ll be working on that module which means that such an optimization won’t help. The real solution here is to wait for us to finish preparation (which we would exactly know when it finishes since sourcekit-lsp would schedule it) but for that we need to implement background preparation.
