Hide color mode preference depending on Accessibility settings

Browse Source 
Currently, when certain Accessibility color transforms are enabled, the
color mode preference radio buttons are disabled. To avoid confusing
users, hide the color mode preference entirely. If the color mode
settings screen is already open when the Accessibility transforms are
enabled, return the user back to the previous screen.

Bug: 77695840
Test: make ROBOTEST_FILTER=ColorModePreferenceFragmentTest
RunSettingsRoboTests -j40
