M12: the table row test checks every cell's height, not only the first

table_rows_of_minimum_height_cells_fill_the_page_at_that_height read the
height of the first widget on the first page only, and counted only the c
cells per page. A shorter last row leaves both the counts and that one
height as they were (checked: with the last row at minH 0.3in the old
assertions pass). It now collects the c and d cells of every row on every
page and asserts each is 28.8pt, with 60 and 20 cells.

Review on #5124 (CodeRabbit, crates/xfa/src/tests.rs).
