Bug 1697034 [wpt PR 27934] - Ensure border-width interpolation test does not yield float values, a=testonly

Automatic update from web-platform-tests
Ensure border-width interpolation test does not yield float values

How border-width values should be rounded in the computed style is an open discussion, per [csswg-drafts issue #5120](w3c/csswg-drafts#5210). This test should not be about testing that behavior but rather whether values are interpolated correctly when `initial` or `unset` is used as a "from" value. To do this we change the "to" value to always have integer values at the tested offsets.
