 * Consolidate messages into groups that have the same id.

 * To ensure that messages are rendered in a deterministic order:
 *  - the messages within a group are sorted by location (file path, then start position)
 *  - the groups are sorted by the location of the first message in the group
 *
 * @param messages the messages to consolidate.
 * @param getMessageId a function that will compute the message id of a message.
 * @returns an array of message groups, where each group is an array of messages that have the same
