CSS Motion Path: New names for properties

The CSS property names for Motion Path properties have changed.

Recent spec update:
https://drafts.fxtf.org/motion-1/
https://github.com/w3c/fxtf-drafts/pull/14

As we already shipped with the earlier names, we alias them to the new names.

motion-offset -> offset-distance
motion-path -> offset-path
motion-rotation -> offset-rotation
motion -> offset

Intent To Ship
https://groups.google.com/a/chromium.org/d/msg/blink-dev/o1C5NzGf9Q0/sbaLF1MbAgAJ

This patch doesn't include deprecation warnings for the old names, or the extra use counter for not-none motion-path discussed in the Intent To Ship.

This patch also doesn't include any of the additional options the spec provides for offset-path (<angle> [contain]) or offset-distance (closest-side / farthest-side / closest-corner / farthest-corner).
(They will be implemented behind a flag, for a future Intent to Ship.)

CSS Motion Path: Use counters for motion properties having effect

A use counter was requested in the Intent thread
https://groups.google.com/a/chromium.org/d/msg/blink-dev/o1C5NzGf9Q0/lJTs_LhRAAAJ
so we know how often motion-path (and/or the motion shorthand) has a
path that is not 'none'. When the path is none, the motion* properties
have no effect.

We also add a second use counter for when offset-path (and/or the
offset shorthand) has a path that is not 'none', or offset-position is
a position, and not 'auto'. It will tell us how often the offset*
properties have an effect.
