[inspect][dart] Add ability to remove a StringProperty.

Per offline discussion, the method has been named "remove" instead of "erase".

Includes contrived example of removing a StringProperty from the example app.

Example output:

$ fx shell iquery --recursive `fx shell iquery --find /hub | grep inspect_mod.cmx | grep root.inspect`
root:
  app-color = MaterialColor(primary value: Color(0xff2196f3))
  home-page:
    background-color = Color(0xffffffff)
    title = Hello Inspect!

$ fx shell iquery --recursive `fx shell iquery --find /hub | grep inspect_mod.cmx | grep root.inspect`
root:
  app-color = MaterialColor(primary value: Color(0xff2196f3))
  home-page:
    background-color = MaterialColor(primary value: Color(0xffcddc39))
    title = Hello Inspect!

$ fx shell iquery --recursive `fx shell iquery --find /hub | grep inspect_mod.cmx | grep root.inspect`
root:
  app-color = MaterialColor(primary value: Color(0xff2196f3))
  home-page:
    background-color = MaterialColor(primary value: Color(0xffff9800))
    title = Hello Inspect!

$ fx shell iquery --recursive `fx shell iquery --find /hub | grep inspect_mod.cmx | grep root.inspect`
root:
  app-color = MaterialColor(primary value: Color(0xff2196f3))
  home-page:
    title = Hello Inspect!
