lib/promrelabel: remove unconditional sorting of the labels in ParsedConfigs.Apply(), since the sorting isnt needed in many places
Sort labels explicitly after calling the ParsedConfigs.Apply() when needed.

This reduces CPU usage when performing metric-level relabeling, where labels' sorting isn't needed.

lib/promrelabel: add SanitizeName() function for sanitizing Prometheus metric names and label names
Optimize this function by using results cache for input strings.
Use this function all over the code.

This is a follow-up for fcffdba9dc

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"
