wpt: Wait for web fonts in onload layout tests

These tests measure layout in onload, which can fire before web fonts
have loaded. Wait for document.fonts.ready first, as in #<!-- nolink -->49493 and
#<!-- nolink -->49502.

This also removes unused Ahem css in related test files.

Testing: These are test changes. With the font response delayed by 1s
(wptserve trickle pipe), the old tests fail on every run and the
updated tests pass on every run.
