feat: improve default haxe_language_server init_options (#3284)

Browse source 
* feat: add '.git' as root pattern for haxe_language_server

* feat: use existing hxml for haxe ls configuration

Previously, it would detect the root dir by matching with "*.hxml", however, it
would use "build.hxml" as the default `displayArguments` even though it may not
exist. This could cause the error:

```
haxe_language_server: -32603: Error: Could not process argument build.hxml (file not found)
Invalid character:
```

Now it will use the first ".hxml" file that is found in the project. It will
only do this if no `displayArguments` value has been set in the `setup()` call,
so it will still respect user set values.

If no hxml file is found, then it uses empty `displayArguments`, which is still
better than a broken configuration.

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.
By default, the language server is configured with the HXML compiler arguments
contained in the first `.hxml` file found in your project's root directory.
If you want to specify which one to use, set the `init_options.displayArguments`
setting:
```lua
lspconfig.haxe_language_server.setup({
-- ...
init_options = {
displayArguments = { "build.hxml" },
},
})
```
]],
default_config = {
root_dir = [[root_pattern("*.hxml")]],
root_dir = [[root_pattern("*.hxml", ".git")]],
init_options = 'default value is set by on_new_config',
},
},
}
