fix(non linear font scaling): fix status bar ui broken when 200% font scaling

As the bug description, the status bar date and battery persentage text ui are broken when 200% font scaling. We adjust the related dimens and update mechanism to assure the textview fontsize/height are correctly updated when font scaling changed.
Besides, we adjust the StatusBarIconView/OngoingPrivacyChip to make the status bar icon image size would also updated to proper size when font scaling changed.
