Hide field, search and chip text with md-visually-hidden again

Plan step 36 review. 52fd65a3 replaced the md-visually-hidden class on
field's spoken counter, search's result count and a bound filter chip's
native checkbox with hooks carrying copies of its clip, on the reading
that a package view writes no class but the interaction classes. The
brief and step 34 let a view write the text classes too, and one shared
source beats three copies: the class is back, the copies and the
data-md-field-live and data-md-chip-native hooks are gone
(data-md-search-status predates them and stays). chip.css keeps its
tooltip.css import.
