Set picker accent color

Enable apps to set a picker accent color which will change the color of
the primary picker elements: add butto, view-selected button, selected
media icons and selected tab colors. Colors of buttons in Preview mode
will also be changed. All the other colors will be set to Material3 baseline
theme.
