Add service API

API

• isStrictlyBeforeVersion(TP, String version)
• isAfterVersion(TP, String version)
• isVersion(TP, String version)

+ same with other TP as parameter instead of just version

• matchesPlatformType(TP, PLATFORM_TYPE type)
• getTargetPlatform(string tpId, boolean filterRestricted, (opt) target packages)
• getDefaultTargetPlatform()

API to adapt (used by annotations on Studio test classes for now, might be useful in the future):

• TARGET_PLATFORM[] getAllPlatforms(boolean ignoreDeprecated,
  boolean ignoreMigrated)
• TARGET_PLATFORM[] getPlatforms(PLATFORM_TYPE type, boolean
  ignoreDeprecated, boolean ignoreMigrated, boolean
  ignorePlatformsWithPackages)
