We will be able to split the LSP modules off later. These LSP modules
will provide the ability to write custom LSP servers and clients in
Swift. The sourcekit-lsp repository will build on top of this new
package to provide an LSP implementation that creates a language server
for Swift and C-based-languages.
`SourceKitServer` now talks to the `SwiftLanguageServer` and
`ClangLanguageServerShim` directly through the `ToolchainLanguageServer`
protocol.
Each individual `ToolchainLanguageServer` manages its own threading.

We have multiple copies of llvm symbols (indexstoredb, indexstore,
llbuild via swiftpm, and sourcekitd), so it's important to keep them
isolated. In practice this seems to have started breaking after we
updated swiftpm and llbuild was added, but it was already a potential
issue before that. The most egregious issue is if you build sourcekit
with assertions, it enables ABI-breaking checks in llvm. On macOS this
dlopen behaviour is already the default.
