arc/gio: Keep ink drop color same for light and dark theme

For buttons in save&reset buttons, keep the ink drop color the same for
both light and dark theme. Re-implement SetUpInkDropForButton because
StyleUtil set up color according to the theme.

Remove the ink drop when save&reset button groups start to drag.

Bug: b/260868602
Test: Inkdrop color stays the same for both dark and light theme.
