This PR improves typing of `DataArray` class methods.
Main change is that `T_DataArray` is used whenever possible.

I have left everything untouched that would cause problems with mypy (there are some mypy bugs) or require larger typing efforts in other areas.

Main problems are `argmin` and `argmax`.","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/6637/reactions"", ""total_count"": 3, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 3, ""rocket"": 0, ""eyes"": 0}",,,13221727,pull

In the recent typing improvements the `engine` argument for `open_dataset` was changed from Str to a Literal of xarrays internal engines.
This will cause problems for all third party backend plugins.

We have several possibilities:

1. I don't know if there is a way to know installed backends at type checking time. Then we could add this support. (I doubt this is possible seeing how dynamic these imports are)
2. Is it possible for these plugins to tell type checkers that their engine is valid, i.e. change the type signature of xarrays function? Then we should add a how-to in the docu.
3. Else we should probably revert to using Str.

Any typing experts here that could help?","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/6632/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed,13221727,issue

- [x] Closes #5382 

Mypy is not able to compute the overloads of to_netcdf properly (too many Unions).
I had to add some `# type: ignore`

I am not sure about the types of
* `concat_dim`
* `combine_attrs`: the `Callable` part is still with Anys","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/6612/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,pull
