/**
* Sets the value at path of object.
* If a portion of path doesn’t exist, it’s created.
* Arrays are created for missing index properties while objects are created
* for all other missing properties.
*
* Path is specified as either:
* - a string of properties, separated by dots, for example: "x.y".
* - an array of properties, for example `[ 'x', 'y' ]`.
*
* This function intentionally mutates the input object.
*
* Inspired by _.set().
*
* @see https://lodash.com/docs/4.17.15#set
*
* @todo Needs to be deduplicated with its copy in `@wordpress/edit-site`.
*
* @param {Object} object Object to modify
* @param {Array|string} path Path of the property to set.
* @param {*} value Value to set.
