Add "Navigate to usage" screenshot action for Terra Wdio tool window

[picimako]

Summary of scope

Currently, although users can navigate from Terra.it and Terra.validates calls to the referenced screenshots, it is not possible the way around.

Solution details

• Add a new context menu action in the Terra Wdio tool window for screenshot nodes called something like "Navigate to/jump to/see usage".
• This action would search for the first Terra.it or Terra.validate call that references the screenshot.
• The Terra calls that would be taken into account are:
  • Terra.it.matchesScreenshot
  • Terra.it.validatesElement
  • Terra.validates.screenshot
  • Terra.validates.element
• It would search only in the spec file that belongs to the particular screenshot.
• Upon using this action, the IDE would open the spec file and would put the caret to the line where the usage is found.
• This action should also take into account nested spec files and screenshots.
