Chore/stackittpr 739 change semver library

[cgoetz-inovex]

Description

I've used the mastermind semver library, since we already had it in our transitive deps

• original implementation worked with KubernetesVersion and MachineImageVersion
  structs
• from both types the version and state fields were used during version
  selection
• introduced interface VersionWithState to cover both cases
• introduce helper funcs for working with this interface: toVersionWithState,
  sortVersions, isDeprecated, isPreview, isSupported
• consolidated getLatestSupportedMachineVersion and
  getLatestSupportedKubernetesVersion into getLatestSupportedVersion
• test cases for these two functions were the same with the only
  difference being the type
• consolidated TestGetLatestSupportedKubernetesVersion and
  TestGetLatestSupportedMachineVersion into TestGetLatestSupportedVersion
• convert to VersionWithState early in call tree
• extracted common parts into latestMatchingVersion
• replace regex check for full version and selectFullVersion
  selectMatchingVersion with constraint and single selectVersion
• move calculation of available out of selectVersion and into error
  branch, when no version could be found

relates to #1234
