[ScrollTimeline] Upstream writing-mode currentTime tests to WPT

This CL upstreams the writing-mode related currentTime tests to WPT.
There are a few mostly non-behavioral changes to the tests in this CL:

  * Some comments were edited for clarity.
  * For tests with more than one assert_equals(), descriptions were
    added to the asserts. This is to help locate failing assert_equal
    lines, as jsharness does not print out the line number of a failure.
  * In a few places we had more than one assert_equals for the same
    scenario (e.g. multiple cases where scroll was after the
    startScrollOffset point). These have been deduplicated.
