 * @remarks
 * The resulting store has a value computed from the parent store in two steps:
 * - first step: the parent configuration is transformed by the adaptParentConfig function (if specified).
 * If adaptParentConfig is not specified, this step is skipped.
 * - second step: the configuration from step 1 is merged (2-levels deep) with the own$ store. The own$ store initially contains
 * an empty object (i.e. no property from the parent is overridden). It can be changed by calling set on the store returned by this function.
 *
 * @param parent$ - optional parent widgets default configuration store.
 * @param adaptParentConfig - optional function that receives a 2-levels copy of the widgets default configuration
 * from parent$ (or an empty object if parent$ is not specified) and returns the widgets default configuration to be used.
 * It is called only if the configuration is needed, and was not yet computed for the current value of the parent configuration.
 * It is called in a tansu reactive context, so it can use any tansu store and will be called again if those stores change.
 * @returns the resulting widgets default configuration store, which contains 3 additional properties that are stores:
 * parent$, adaptedParent$ (containing the value computed after the first step), and own$ (that contains only overridding properties).
 * The resulting store is writable, its set function is actually the set function of the own$ store.
