Allow plat_Highlight() to distinguish between moving a piece and showing attackers/defenders.

Notes:
- The color isn't usable for this distinction as HCOLOR_ATTACK is used for both scenarios.
- This change doesn't make use of the new distinction on the C64. One option would be to use different brackets for the two scenarios.
