This change splits `NodeKind::IdentifierName` into separate node kinds
depending on whether the identifier is followed by parameters, and
similarly splits `NameQualifier` based on whether the qualifier has
parameters. This enables us to only push a pattern block when it's
actually needed, rather than "defensively" pushing one when it might be
needed.

I'm trying to make the LSP look more like the rest of the toolchain. I'm
trying to separate the handlers from the transport layer, and remove the
multiple inheritance aspect. Also fixing some style issues, switching to
`Map`, and removing an unnecessary copt.
I'm using `Context` for the central object for consistency with other
portions of the toolchain. In order to get the `handle_*` files working,
I'm using LLVM's registry class. It has a quirk that I can't register
two registries in the same cpp file, so there are two one-line cpp
files.
In order to help show the delta (or lack thereof) for actual
implementation, I've copied server.cpp over handle_* and undone that in
two commits. See the third and fourth commits on the PR history for
that.
