Revert "Migrate some preference theme attributes from SettingsLib"

This reverts commit 77a89a6ca44ffd85f3bfba6cb42d089c288ea196.

Reason for revert: in b/70031670 we discovered some problems in
the support library side change (ag/3136307), and it will take a
little while to fix those problems so we need to temporarily
revert the support library changes to unblock a push of the
support library to google3.
