Layout tests: start every test with test_fonts and refit three fixtures to the pinned fonts

Adds crate::test_fonts() to the 95 layout tests that lacked it (several arrived
with upstream merges). Three fixtures were sized for installed fonts and failed
with the pinned set: exact_row_moves_whole (one line less of filler),
an_at_least_row_at_the_top_of_a_page_splits_instead_of_moving_on (60 lines so
the split row does not spill an empty page) and the inline text box test
(FILLER 16).
