Add a `sourcekit-lsp version` command that outputs the SourceKit-LSP version #1424

Ideally, this would output the corresponding Swift version (eg. 6.0) and the commit hash from which it was built. Maybe we can use a build plugin to get the commit hash and the Swift version from the current branch name.

We should be able to do this by

Reading Context.gitInformation?.currentCommit in the package manifest
Passing that information into a C modules using -D
Calling a function in the C modules to return the info

Context.gitInformation?.currentCommit is only available with swift-tools-version 6.0, so we can only do this after we require Swift 6 (because I don’t want to have two different package manifests to maintain just for this feature).
