Questions that needs to be resolved:

- [ ] Can these properties change during the lifetime of the class? If so the cache needs to be reset when that happens.

Notes
* Mixin classes makes it difficult to cache properties. For example `ndim` in `NdimSizeLenMixin` cannot be easily be replaced with `cache_readonly`.","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/5540/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,pull

* `get_axis_num` seems slow, avoid triggering it unnecessarily for example when using 1d arrays.
* .copy(deep=False) is the bottleneck for 1d arrays. Not sure if it can be dealt with though.
