Give cursor radio buttons their own sequential IDs in propsheet (#6231)

For a radio button group to work properly, they need sequential IDs.
This moves the cursor radio buttons on the `conhost` property sheet to
be sequential.

## Detailed Description of the Pull Request / Additional comments
- `CheckRadioButton` takes a contiguous group of IDs. It will set one
  item in the list and then uncheck the rest. When a new one was added
  to the group, it was added to the end of the segment in the IDs file,
  but not immediately after the existing radio buttons. This means it
  accidentally turned off all the other buttons in the middle.
- To resolve this, I moved all the cursor buttons into their own
  sequential group number and I deprecated the old values.

## Validation Steps Performed
- [x] Ensured that the "Discard Old Duplicates" value was set in the
  registry, walked through debugger as `conhost` packed the `TRUE` value
  into the property sheet blob, walked through the property sheet
  `console.dll` as it unpacked the `TRUE`, then observed that the
  checkbox was actually set instead of getting unset by the
  `CheckRadioButton` call that went from 107 to 119 and accidentally
  unchecked number 112, `IDD_HISTORY_NODUP` even though I swear it was
  just set.
