Instead of storing build settings inside the language servers based on update notifications from the build system, always call into the `BuildSystemManager` to get the build settings.
Overall, I think this is a much clearer separation of concerns and will allow us to remove `SourceKitServer.documentToPendingQueue` in a follow-up commit as `SwiftLanguageServer` can always directly call into `BuildSystemManager` to get build settings and we don’t need to wait for the initial notification to receive the first build settings.
This requies `BuildServerBuildSystem` to keep track of the build settings it has received from the BSP server.
`ClangLanguageServer` still caches build settings locally. `ClangLanguageServer` will change to the same pull-based model in a follow-up commit.
Unfortuantely, we have a few potential out-of-order exeuction possibilities while we migrate everything else to also be asyncronous. But those should be low-probability issues that we can fix in follow-up commits, so I think it’s fine for now. All of these places are marked with `FIXME: (async)`
The asyncification changes caused some non-deterministic test failures. I believe that some of these are due to race conditions that are the result of the partial transition to actors.
Instead of merging the asyncification piece by piece, I will collect the changes asyncification changes in a branch and then qualify that branch througougly (running CI multiple times) before merging it into `main`.

Since we moved `BuilderServerHandler` and `ClangLanguageServerShim` to directly conform to `MessageHandler`, `SourceKitServer` was the only type inheriting from `LanguageServerEndpoint` and we can thus remove the type.
I noticed that the initial package loading can take ~5s. It’s good behavior to inform the client that sourcekit-lsp is busy reloading the package, showing the user that semantic functionality might not be ready yet.

A declaration request is similar to a definition request, except that it is expected to return (potentially) many results across the workspace for a given reference. For example, an inline function or macro may have many declarations in the workspace, but only one "good" or canonical definition. For now, this is only implemented by forwarding the request on to clangd since I'm unfamiliar with a SourceKit query for this.
For languages like Swift that lack such a sharp declaration/definition split, we could potentially use this request to provide navigable metadata on linked definitions. For example, the declaration for a type reference would include all extensions of that type in the workspace.
Rather than treating the filename as an opaque string and splitting on
`/`, use `AbsolutePath` to perform the `basename` operation on the path.
This ensures that we split the path properly on platforms which do not
use the POSIX path separator `/`.
Explicitly import interfaces from TSCBasic which now allows us to
identify all the swift-tools-support-core interfaces which are in
use in SourceKit-LSP.
