Germán Jabloñski d963e6a54c feat: orderable collections (#11452 )

Closes https://github.com/payloadcms/payload/discussions/1413

### What?

Introduces a new `orderable` boolean property on collections that allows
dragging and dropping rows to reorder them:

### Why?

[One of the most requested
features](https://github.com/payloadcms/payload/discussions/1413).
Additionally, poorly implemented it can be very costly in terms of
performance.

This can be especially useful for implementing custom views like kanban.

### How?

We are using fractional indexing. In its simplest form, it consists of
calculating the order of an item to be inserted as the average of its
two adjacent elements.
There is [a famous article by David
Greenspan](https://observablehq.com/@dgreensp/implementing-fractional-indexing)
that solves the problem of running out of keys after several partitions.
We are using his algorithm, implemented [in this
library](https://github.com/rocicorp/fractional-indexing).

This means that if you insert, delete or move documents in the
collection, you do not have to modify the order of the rest of the
documents, making the operation more performant.
