The grok processor REST endpoint returns the bundled grok patterns in an undetermined order. This PR changes the default behavior to return them in the order in which they were read from disk which preserves the natural grouping of related patterns such as "S3_ACCESS_LOG" and "ELB_URI" for AWS-related patterns though they share no common prefix. An option to return all patterns sorted by key was also added.
Resolves #40819.
