lib/promrelabel: optimize action: {drop,keep,labeldrop,labelkeep} with anchored regex prefix
The following commonly used relabeling rules must work faster now:

- action: labeldrop
  regex: "^foo.+$"

- action: labeldrop
  regex: "^bar.*"

lib/promrelabel: optimize action: {labeldrop,labelkeep,keep,drop} with regex containing alternate values
For example, the following relabeling rule must work much faster now:

- action: labeldrop
  regex: "foo|bar|baz"
