What problem does this address?

#49094 covers development of Terms Query block in its basic form. One of the discussed features is Include / Exclude controls so user can specify terms they want to display or omit.

What is your proposed solution?

Requirements:

• Inputs:

  • Text Input with "chips" where user can list terms they want to include/exclude
  • Use FormTokenField as in other similar cases

• "Include" control

  • Including at least one item means that only terms listed in this input are displayed (and its descendants if "Show only top level" is disabled)

• "Exclude" control

  • Hides specific terms even if it matches other criteria.
  • Hides ONLY this specific term (doesn't impact descendants - @mikachan, how do you feel, is that how you see it? Or should it also exclude descendants? I think the latter would be too limiting 🤔)
