 * Gets a list of post meta fields with their values and labels
 * to be consumed in the needed callbacks.
 * If the value is not available based on context, like in templates,
 * it falls back to the default value, label, or key.
 *
 * @param {Object} select  The select function from the data store.
 * @param {Object} context The context provided.
 * @return {Object} List of post meta fields with their value and label.
 *
 * @example
 * ```js
 * {
 *     field_1_key: {
 *         label: 'Field 1 Label',
 *         value: 'Field 1 Value',

 *         value: 'Field 2 Value',
