Update text size of few UI components

Updated "Photos" and "Albums" chip text size to 16sp. Previously, this
text size was lower than date header's text size, which made it
highlight date header over chips.

Update style for "deselect" button and "add" button to match
borderlessButtonStyle and materialButtonStyle respectively.
