Perennial deciduous fruit trees in CLM

I've been working on a crop development to consider perennial deciduous fruit trees in CLM5 to model fruit orchards ([the published paper](https://gmd.copernicus.org/articles/15/5167/2022/)).
The development includes a new phenology subroutine for perennial deciduous woody crops and considers the typical phenological development, carbon allocation and management practices for fruit trees grown in commercial orchards. I've also parameterized a new crop PFT for apple trees.
This issue relates to #1908 and I've been in touch with Ashehad and Yuanchao in the early stages of my development. I've used some of their features in a similar way (e.g. a perennial flag, annual harvest implementation, orchard rotation).
Thus far the model was developed, calibrated and tested on the point scale.

Best,
Olga
