Bug 1742859 [wpt PR 31735] - Add tests for letterspacing and wordspacing with different units, a=testonly 

Automatic update from web-platform-tests
Add tests for letterspacing and wordspacing with different units

After changing letterspacing and wordspacing to accept strings,
test if they work with different length units, ex: px, mm, cm, inch, em.

Bug: 1263632
