[Component] More interaction granularity for command button actions

[Kirill Grouchnikov]

Same as in Radiance:

• Auto-repeat action. Enabled with autoRepeatAction boolean, initial delay configured by autoRepeatActionInterval, subsequent delays configured by autoRepeatSubsequentInterval
• Fire action trigger, configured with actionFireTrigger and the new ActionFireTrigger enum that has three values:
  • OnRollover to fire action on rollover
  • OnPressed to fire action on press
  • OnPressReleased to fire action on press release (the default)
