As pointed out in https://github.com/jbusecke/cmip6_preprocessing/issues/5, xarray appears to be very strict during the *encoding* and *decoding* steps even when there are (harmless) discrepancies between `missing_value` and `_FillValue`. For instance, when dtypes of `missing_value` and `_FillValue` are different, xarray gives up: 


```python
In [74]: from xarray.coding import variables

In [76]: import xarray as xr                                                                    

In [77]: original = xr.Variable( 
    ...:         (""x"",), 
    ...:         [0.0, -1.0, 1.0], 
    ...:         encoding={""_FillValue"": np.float32(1e20), ""missing_value"": np.float64(1e20)},

Libraries, including `xarray`, register backends via `entrypoints`. Xarray adds an EntryPoint ""group"" in its `setup.py`. Third party libraries add items to that group in their `setup.pys`. 

Xarray and the third-party library don't need to talk to each other directly to register a backend. They talk through `pkg_resources`.

For instance, `hvplot/holoviews` would add an EntryPoint for `xarray_plotting_backends` in its setup.py:

```python
entry_points={""xarray_plotting_backends"": ['holoviews = hvplot:plotting']}
```

and xarray users should be able to achieve what @jsignell proposed in #3553:

> ```python
> import xarray as xr
> air = xr.tutorial.open_dataset('air_temperature').load().air
> xr.set_options(plotting_backend='holoviews')
> 
> air.isel(time=500).plot()
> ```

Currently, the CI runs both on a user's fork and `pydata/xarray`. This leads to duplicate runs and the user is flooded with GitHub notifications in case of failures... This PR addresses this issue by making sure the workflows are triggered on `pydata/xarray` only.

It turns out that pushes on main branch result in [an invalid package version](https://github.com/pydata/xarray/runs/2519311659). To address this issue, I am disabling the `push` event trigger on the release workflow

~~The ""Xarray-lite"" name is a placeholder for the time being. we have considered two main candidates for the package's name: ""narray"" and ""yarray."" feedback on the proposed names or other suggestions is welcome.~~

this pull request introduces the initial prototype for `NamedArray` as discussed in issue #8073. the intention is to approach the implementation in multiple phases through separate pull requests. the main objectives of this PR are as follows:

1. creation of a new class, `xarray.named_array.NamedArray`, which will encompass most of the necessary functionality for the lightweight version of `xarray.Variable`. As a result, `xarray.Variable` will inherit from this class and implement specific functionality related to xarray.

2. removal of all imports of internal Xarray classes and utilities from the `xarray.named_array` sub-package. the aim is to eliminate dependencies on anything within `xarray.core`. This will facilitate the future goal of moving `named_array` into its own standalone package, with `xarray` then depending on it.

Now, `__getitem__` exclusively handles basic indexers, aligning with points 3 and 4 of the plan:

- as per point 3, lazy indexing arrays will now implement `__getitem__` solely for basic indexing. For orthogonal indexing, .oindex will be used, and for vectorized indexing, .vindex will be utilized.
- following point 4, IndexingAdapter classes have been updated to consistently implement `__getitem__`, `.oindex`, and `.vindex`

This pull request is the first part of migrating the indexing and broadcasting logic from `xarray.core.variable` to `xarray.namedarray`. I intend to open follow-up pull requests to address additional changes related to this refactoring, as outlined in the [proposal for decoupling lazy indexing functionality from NamedArray](https://github.com/pydata/xarray/blob/main/design_notes/named_array_design_doc.md#plan-for-decoupling-lazy-indexing-functionality-from-namedarray).

this PR builds towards 

- https://github.com/pydata/xarray/pull/8870
- https://github.com/pydata/xarray/pull/8856

the primary objective is to partially address 

>  2. Implement fall back `.oindex`, `.vindex` properties on `BackendArray` base class. These will simply rewrap the `key` tuple with the appropriate `*Indexer` object, and pass it on to `__getitem__` or `__setitem__`. These methods will also raise DeprecationWarning so that external backends will know to migrate to `.oindex`, and `.vindex` over the next year.

As noted in https://github.com/pydata/xarray/issues/8909, the use of `.oindex` and `.vindex` properties in coding/* appears to have broken some backends (e.g. scipy). This PR reverts those changes. We plan to bundle these changes into a separate backends feature branch (see [this comment](https://github.com/pydata/xarray/pull/8885#issuecomment-2036001828), which will be merged once we are confident about its impact on downstream dependencies.
