Bug 1550205 [wpt PR 16390] - Add more offsetLeft/offsetTop for tests empty/space inline elements, a=testonly

Automatic update from web-platform-tests
Add more offsetLeft/offsetTop for tests empty/space inline elements

Besides the test for empty inline elements, this CL also adds tests
for inline elements containing spaces that are leading/trailing of the
lines, to test that offsetLeft/offsetTop still works regardless of
space collapsing.

Also rename the tests to follow the common naming convention.
