Subject: Add support for the Haxe Language Server

This adds support for the language server used by the Visual Studio Code
Haxe Extension: https://github.com/vshaxe/haxe-language-server

I've found this language server to be tricky to properly attach to, but
this config should do the trick.

+
+The Haxe language server can be built by running the following commands from
+the project's root directory:
+
+    npm install
+    npx lix run vshaxe-build -t language-server
+
+This will create `bin/server.js`. Note that the server requires Haxe 3.4.0 or
+higher.
+
+After building the language server, set the `cmd` setting in your setup
+function:
+
+```lua
+lspconfig.haxe_language_server.setup({
+  cmd = {"node", "path/to/bin/server.js"},
+})
+```
+
+By default, an HXML compiler arguments file named `build.hxml` is expected in
+your project's root directory. If your file is named something different,
+specify it using the `init_options.displayArguments` setting.
